Question

A bag contains 4 white, 3 blue, and 5 red marbles. find the probability of choosing 3 blue marbles in a row if the marbles are replaced

Answer 1

There is 12 possible outcomes. also, there is a 3/12 chance of getting a blue marble.
The probability of choosing 3 blue marbles in a row:
`(3)/(12)* (3)/(12) * (3)/(12)= (1)/(4) *(1)/(4)* (1)/(4) = (1)/(64) =0.015625` ( or 1.5625 %)
