Question

There is a stack of 8 cards, each given a different number from 1 to 8 . Suppose we select a card randomly from the stack, replace it, and then randomly select another card. What is the probability that the first card is an odd number and the second card is greater than 4?

Answer 1

Three things you need to know
there are 4 even cards
there are 4 cards greater than 4
The third thing is you get to replace the cards.

4/8 * 4/8 = 1/4
