#24, the wording of the question throws me off.

I believe that the question is asking if there is a large variation between the results or not, as it asks if the births are with equal frequency. Since the largest is 72 and the smallest is 43 (for a 29 number difference), it doesn't seem like they are with the same frequency

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
