2. how did you got 8/24 * 4/23 = "4/69"?????????????????????

8 x 4 = 32

24 x 23 = 552

3. first test is oatmeal
there are 8 oatmeal cookies out of the 24 in the jar so the probability of pulling an oatmeal cookie out is 8/24 = 1/3

Then we have 23 cookies in the jar and 12 are chocolate chip (sorry I did peanut butter)
so
1/3 * 12/23 = 4/23
