What is the probability of drawing a red and blue marble with replacement?

If the marble is not “replaced”, the probability of the second drawing changes, since there are less marbles in the jar. The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4.

What is the probability of drawing 2 red marbles with replacement?

On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue.

What is the probability of picking green marble from the jar?

0
The probability of selecting a green marble at random from a jar that contains only green, white and yellow marbles is 0.

What is the total number of marbles in the jar?

Hint: Use the probability of occurrence of green & white marbles to find the number of green & white marbles & hence find total number of marbles. Let us suppose a jar which contains green, white and yellow marbles only. Also, given that there are 10 yellow marbles in the jar.

What is the probability that 2 randomly chosen marbles are not pink?

To obtain the probability that is asked, simply compute 1 – (2/9) = 7/9. The probability that the 2 randomly chosen marbles are not both pink is 7/9.

How many marbles are in a bag of marbles?

A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles. What is the probability of randomly selecting a blue marble, then without replacing it, randomly selecting a green marble? | Socratic A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles.

What is the probability of drawing a red on the first?

On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue.
