Acard is drawn from a deck of 52 cards, what is the probability that it is a number 2?

The answer in fraction form is exactly 1/13
The approximate answer in decimal form is 0.076923

To get this answer, note how there are four cards that have "2" on them. This is out of 52 total. So we divide the values: 4/52 = 1/13. Don't forget to fully reduce as much as possible. 

To go from 1/13 to 0.076923, you would use a calculator or long division
