Answer 1

In order to do this problem and solve it efficiently we need to recognize out of these 12 employees how many have a birthday in the first 100 days of the year

after calculating you should get that 5 out of the 12 of these employees have birthdays in the first hundred days of the year

the rest is simple

simply divide 5/12 and you should get 0.41
16 (with a bunch of sixes)

go ahead and round up to 0.417 and that should lead you to your answer

so the correct answer is a: 0.417

Answer 2

344 180 274 358 64 121 32 96 151 275 93 49

Out of the 12 numbers above, 5 (in bold type) are 100 or less.

5/12 = 0.41666...

Answer: 0.417
