4/8 odd numbers you will pick.

Katherine · Answer 2

Probability you'd pick an odd number:

1 2 3 4 5 6 7 8

Odd numbers: 1 3 5 7

There are 4/8 odd numbers so probability is 4/8 first pick.

Card is put back so you still have 8 cards. Probability greater than 6:

7 and 8 are greater than 6, so that's 2 out of 8 cards. Probability: 2/8

Multiply both probabilities together: 4/8 x 2/8 = 8/64 = 1/8
