Question

A bag of marbles contains 5 red, 3 blue,2 green and 2 yellow marbles.

What is the probability that you choose a blue marble and then another blue marble, assuming you replace the first marble??
A.1/24
B.1/16
C.1/2
D.3/4
Please help

Answer 1

i would definitely say the probability is 1/6

Answer 2

Answer:
`(1)/(16)`

Explanation:

Given: The number of blue marbles = 3

The total number of marbles =
`5+3+2+2=12`

Then the probability that you choose a blue marble and then another blue marble, assuming you replace the first marble =

`=(3)/(12)*(3)/(12)=(1)/(16)`

Hence, the the probability that you choose a blue marble and then another blue marble, assuming you replace the first marble =
`(1)/(16)`
