Question

A bag contains five red marbles, five blue marbles, and three yellow marbles. You randomly pick three marbles without replacement. What is the probability that the first marble is red, the second marble is blue, and the third marble is yellow?

Answer 1

Explanation:

We have a total of 13 marbles.

So the probability that the first marble is red.

`p(r) = (5)/(13)`

Since, we pick without replacement.

We have 12 marbles left so the probability that our second marbles is blue is

`p(b) = (5)/(12)`

So after that. we have 11 marbles left so we get

`p(y) = (3)/(11)`
