Question

Given a bag of 5 blue, 3 green, and 8 red marbles.. What is the probability of picking a blue

and then a green with NO replacement

Answer 1

`b = 5, \: g = 3, \: r = 8`

`total = 5 + 3 + 8 = 16`

`p(b) = (5)/(16)`

`p(g |without \: replacement|) = (3)/(16 - 1) = (3)/(15) = (1)/(5) \\`

`p(b \: and \: g) = (5)/(16) * (1)/(5) = (1)/(16)`
