Question

Jim has the following tiles in a bag:

A, A, B, B, B, C, C
Jim takes a random tile.
PART A.) Calculate the probability that the tile that he takes
will be a C.
Write your answer as a fraction in simplest form.
PART B.) Calculate the probability that the tile he takes is a B OR C.
Write your answer as a fraction in simplest form.

Answer 1

5/7

Explanation:

If the tiles are A, A, B, B, B, C, C, then there are 7.

That makes the probability of an A: 2/7

The probability of an B: 3/7

And the probability of an C: 2/7

The probability of a B or C combines 2/7 + 3/7 so: 5/7
