What is the probability of choosing a A black marble and then a white marble if the first marble is replaced?

Two marbles are chosen without replacement. The probability of selecting a black marble and then a white marble is 0.34, and the probability of selecting a black marble on the first draw is 0.47.

When two sided dice are rolled There are 36 possible outcomes?

When two dice are rolled, there are now 36 different and unique ways the dice can come up. This figure is arrived at by multiplying the number of ways the first die can come up (six) by the number of ways the second die can come up (six). 6 x 6 = 36.

Is coin tossing a mutually exclusive event Why?

When tossing a coin, the event of getting head and tail are mutually exclusive. Because the probability of getting head and tail simultaneously is 0. In a six-sided die, the events “2” and “5” are mutually exclusive. We cannot get both the events 2 and 5 at the same time when we threw one die.

What is the probability of drawing two red marbles?

Assuming we draw a red marble from the bag, there is one less red marble and one less total marble. This means for the second drawing there is a 2/11 chance of drawing a red marble. This means the probability of drawing two red marbles is 1/22.

When rolling two six-sided dice What is the probability that the sum of the dice is 6?

5/36
Answer: The probability of rolling a sum of 6 with two dice is 5/36.

When you roll two dice there are 36 possible outcomes What is the probability of rolling two dice and the sum is not 7?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

What is the chance of two blue marbles being 7/17?

Since you have two blue marbles, this means it is without replacement (with replacement gives a different answer). To start off with, 7/17 are blue. With one less marble and one less blue, the chance for the second is 6/16, so multiplying these together, 7/17 * 6/16 = 21/136. Comment on David Severin’s post “Since you have two blue m…”

How many marbles are in a bag of marbles?

A bag contains 3 white, 4 black, and 2 red marbles. Two marbles are drawn from the bag. If replacement is not allowed, what is the probability that the second marble drawn will be red? I disagree Stack Exchange Network
