Question

Does anyone know this? There are 25 students names in a hat. You choose 5 names. Three are boys names and two are girls names. How many of the 25 names would you expect to be boys names?

Answer 1

The answer is probably 15 if you use ratios. So 3x5 equals 15

Answer 2

I would expect there to be 15 boy names and 10 girl names.

Explanation:

There is a 3 to 2 ratio between boy and girl names, and the only numbers that add up to 25 with that ratio are 15 and 10
