alex has 5 t-shirts in the drawer. 2 are white, and the rest are black. He will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. What is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?

Answer:

24%

Explanation:

Lets consider it.

2 are white, and 3 are black.

2/5 chance of him getting white, and 3/5 chance of him getting black

So he successfully gets white on his first try.

2/5

Then he successfully gets black on his second try

2/5 * 3/5, or 6/25, or 24% of him getting white, then black.

This is all just middle school math, and I hope it helps :)
