What is the probability of getting a purple marble?

The probability is about 9.33\% .

What is the probability that the marble is not yellow?

The probability that the marble is not yellow is 0.8.

What is the probability of drawing two yellow marbles in a row?

The probability of it being yellow is again 7 in 16. Now the probability of getting yellow marble twice is the product of the two probabilities, or (7/16)*(7/16), which equals 0.1914, which is 19.14\%.

What is the theoretical probability of randomly drawing a red marble and then a green marble?

The probability of randomly drawing a red marble and then a green marble is 1/6 . The probability of not drawing a blue marble is 20\%. The probability of drawing a green marble is the same as the probability of drawing either a red or a blue marble.

What is the probability that the marble will be any one Colour?

HENCE, the probability of getting any one colour is 1.

How do you find the probability of drawing marbles?

The probability of drawing a red marble = 2/5. The probability of drawing a blue marble = 1/5. The 1/5 probability of drawing a blue marble assumes all 5 marbles are in the jar.

What is the theoretical probability of randomly drawing a red marble?

The probability of getting red is 2/3.

How many more green marbles does John have to take?

If there are going to be more blue than green marbles after John’s 13 marbles, he has to take at least 4 more green marbles than blue marbles, because right now there are 3 less blue marbles.

How many marbles are in a jar of marbles?

A jar of marbles has 125 marbles in it. 25 are blue marbles, 65 are red marble, 15 are green marbles and 20 are yellow marbles. What is the probability that the first three marbles picked are green or blue? Probability of each event = (# green marbles + # blue marbles)/ Total # of Marbles

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 do you solve for the difference in marbles?

We can also solve this as an inequality. You take the difference in marbles, which is 3, which means you need the difference in green and blue marbles to be greater than 3, or at least 4. You have b + g = 13 and g – b > 3, where b and g are positive integers.
