What is the probability of picking a 4 and then picking a number less than 5?
Simplify your answer and write it as a fraction or whole number.

There are FOUR 4's in a deck of 52

4/52 = 1/13 chance

Second card less than 5 ?

4 aces 4 two's 4 threes and 4 fours

16/ out of 52 = 16/52 chance = 4/13 chance

1/13 * 4/13 = 4/169 chance of picking as questioned
