Question

Finding Probabilities of Compound Events
In Sal’s sock drawer, there are 2 red, 2 blue, 2 yellow, 2 black, and 2 green socks. If he randomly picks one sock from the drawer, and then another, which fractions should Sal multiply to find the probability of choosing a pair of green socks?

Answer 1

First pick green: 2 out of 10 → 2/10.
Then pick the other green: 1 out of 9 → 1/9.

So multiply 2/10 × 1/9 = 2/90 = 1/45.
