Question

A drawer contains 20 socks. 10 are black. 6 are blue. 4 are red. Two socks are taken out at random. What is the probability that both of them are red?

Answer 1

3/95


Step-by-step explanation:
The chance of picking out a red sock the first time is 4/20. The second time, it is 3/19 as there is one less red sock and therefore one less sock on the drawer.
3/19 x 4/20 = 3/95 or 0.0316 (3 s.f)
