Question

I WILL MEDAL!!
Brian has a bag that contains 14 red marbles and 12 yellow marbles. He selects a marble at random, and then, without replacing the first one, selects another marble at random.

What is the probability that Brian selects a red marble and then a yellow marble? Round your answer to the nearest percent.

P(red and yellow) ≈ %

Answer 1

You need to find the ratio and turn it into a percentage
so you have 14 red and 12 yellow, Do you know what the ratio for the marbles?

Answer 2

is simply a case of

P(red) x P(yellow)

but remember when you select the 2nd marble there is 1 less to choose from

Answer 3

is it 14/26 * 12/25

Answer 4

that's correct, when you get the answer convert it to a percentage
