2 cards are drawn from a standard deck without replacement. What is the probability that at least one of the cards drawn is an ace? Express your answer as a fraction or a decimal number rounded to four decimal places.

Step-by-step explanation:

In a standard deck there are 52 cards in total and there are 4 aces.

Two cards can be drawn from the 52 cards in ways.

There are (52 - 4) = 48 cards rather than the aces.

From these 48 cards 2 cards can be drawn in ways.

The probability of choosing 2 cards without aces is .

The probability of getting at least one of the cards will be an ace is .

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
