Question

A bucket contains 5 green tennis balls, 2 yellow tennis balls, and 6 red tennis balls. Tony removes 3 tennis balls, with replacement, from the bucket shown.

What is the probability that the first tennis ball is yellow, the second tennis ball is green, and the third tennis ball is red?

Answer 1

`(5)/(143)` chance

Explanation:

Chance of getting yellow first time:
`(2)/(13)`

Chance of getting green without replacement from yellow:
`(5)/(12)`

Chance of getting red without any replacement:
`(6)/(11)`

`(2)/(13) *(5)/(12) *(6)/(11) =(60)/(1716) =(10)/(286) =(5)/(143)`
