Please solve 2

Shuffle a deck of cards (a total of 52 cards without the jokers) and turn over the first card. How many outcomes are in the sample space? How many outcomes are in the event that the first card is not a heart? What is the probability that the first card is not a heart? (note that all outcomes are equally likely to happen)

Solution

Since in a deck of 52 cards, the number of outcomes will be 52 in the sample space.

And the outcomes that the first card is not a heart are 39.

The probability that first card is not a heart is 39/52 = 0.75
