A Jar Contains 5 Blue Marbles, 8 Red Marbles, 4 White Marbles, And 3 Purple Marbles. Suppose You Pick A Marble At Random Without Looking. The number of 2 green sock combinations is zero, because there is only one green sock. So the total number of combinations of the same color is 6+3+1=10. The total number of ways to pick any two socks out of 10 is combin(10,2)=10!/(8!*2!) = 10*9/2=45. So the probability of choosing two of the same color is 10/45 = 22.22%. .

Assuming the coin is fair, each of the outcomes will occur roughly the same number of times in many repeats of the experiment. The probability of "two tails" will be 3/8.

Probability. How likely something is to happen. Many events can't be predicted with total certainty. The best we can say is how likely they are to happen, using the idea of probability. Tossing a Coin. When a coin is tossed, there are two possible outcomes: heads (H) or ; tails (T) We say that the probability of the coin landing H is ½ Let's break it down into cases. Case 1: you pick a white marble, followed by a blue marble. Initially, there is a 2/5 chance of picking a white marble. On your second pull, since we are not replacing marbles, there's a 3/4 chance that you pick a b...3. The probability that a customer order a hamburger is 0.3.

Now suppose that the die is rolled and we are told that the event Ehas occurred. This leaves only two possible outcomes: 5 and 6. In the absence of any other information, we would still regard these outcomes to be equally likely, so the probability of F becomes 1/2, making P(FjE)=1=2. 2

The only other way is to first pick a white then a black, which means one of 3 whites out of 7 and then one of 4 blacks out of 6, for a probability of 3/7 * 4/6, another 12/42. These two scenarios are disjoint and cover all possible ways of picking one of each color in two picks. So the total probability is the sum 12/42 + 12/42 = 24/42.
Now that you have 49 red marbles left in the other jar, you have a nearly even chance of picking a red marble (49 out of 99). So let’s calculate the total probability. P( red marble ) = P( Jar 1 ) * P( red marble in Jar 1 ) + P( Jar 2 ) * P( red marble in Jar 2 )
B. What is the probability of drawing 3 marbles without replacement in a row of the same color without replacement? 5. James has 3 dimes, 4 pennies, and 2 quarters in his pocket.

The probability of pulling a red marble would be calculated by taking the total number of red marbles and dividing it by the total number of marbles. OR The only other way is to first pick a white then a black, which means one of 3 whites out of 7 and then one of 4 blacks out of 6, for a probability of 3/7 * 4/6, another 12/42. These two scenarios are disjoint and cover all possible ways of picking one of each color in two picks. So the total probability is the sum 12/42 + 12/42 = 24/42.

Expected value multiplies the probability of each outcome by the possible outcome. For example, in a dice game, rolling a one, three or five pays $0, rolling a two or four pays $5, and rolling a six pays $10. In dice, the probability of rolling a one through six is 1/6 each.
Step # 2: Now, you have to multiply the decimals from step 1 together.85 x .45 = .3825 or 38.35 percent. So, the probability of individuals having a deductible of over $1,000 is 38.35%. That’s how to calculate probability of two events occurring together! Probability of Two Events Occurring Together – Independent probability: To determine the probability of two dependent events, multiply the probability of the first event times the probability of the second event after the first event has occurred. Practice: Dependent Events Suppose you draw two marbles from a bag containing 6 red, 3 green, 2 yellow, and 4 blue. You pick the second one without replacing the first one. Consider a jar with 4 black marbles and 6 white marbles. If you pull out 2 marbles from the jar randomly, one at a time, without replacing the first marble, what is the probability that both marbles will be white? Start by approaching the problem the same as you would with independent events. The probability of the first marble being white is:
Oct 17, 2019 · In our earlier sample problem, we calculated the probability of picking four blue marbles as .007. Putting these together, the probability of picking four marbles of the same color: P(all 4 red ∨ all 4 white ∨ all 4 blue) = P(all 4 red) + P(all 4 white) + P(all 4 blue) = .0012 + .0587 + .007 = .0669 (approximately)

Nov 13, 2016 · First pick 1 marble, ANY marble. For this first step, picking either color is equally likely. At this point, there are 3 marbles remaining in the jar. 1 marble is the SAME color as the first marble you selected, and 2 marbles are a DIFFERENT color from the first marble you selected. So, it's more likely that the two marbles will be DIFFERENT colors
Feb 14, 2019 · In mathematics, we express the probability of the two types of marbles in the following ways: P(yellow) = 95/100 or 95% P(red) = 5/100 or 05% Assuming we reset the number of marbles in each trial ... The only other way is to first pick a white then a black, which means one of 3 whites out of 7 and then one of 4 blacks out of 6, for a probability of 3/7 * 4/6, another 12/42.

But the coin has not changed - if it's a "fair" coin, the probability of getting tails is still 0.5. Dependent Events Two (or more) events are dependent if the outcome of one event affects the outcome of the other(s). Thus, one event "depends" on another, so they are dependent. Example I draw two cards from a deck of 52 cards.
