An odd number is chosen randomly from a set of index cards labeled 1-8. A second odd number is chosen without the first index card being replaced. What is the probability of both events occurring?

Respuesta :

1 thru 8.....there are 4 odd numbers (1,3,5,7).....
probability of picking an odd number on first pick is 4/8
without replacement
probability of picking an odd number on 2nd pick is 3/7

probability of both events happening : 4/8 * 3/7 = 12/56 = 3/14
