Question

Twenty-five cards are numbered from 1 to 25 and placed in a box. One card is selected at random and not replaced. Another card is randomly selected. What is the probability of selecting two even numbers?

Answer 1

11/50

Explanation:

In draw 1,

Favourable outcome / Total number of possibilities = 12/25

In draw 2,

Favourable outcome / Total number of possibilities = 11/24

Total chance of getting 2 even numbered cards = 12/25 * 11/24 = 11/50
