Question

There are five different cards numbered 1 through 5. Assume the cards are randomly chosen. If the first card picked was a 2 and it was not placed black in the pile, then what is the probability the second card chosen will be a 4?

Answer 1

P(4) = 1/4

Explanation:

There are 5 cards

2 gets taken away

There are 4 cards

The cards remaining are 1,3,4,5

4 only comes up once therefore the probability is 1/4.
