Question

Joe works on an assembly line that fills boxes with various toy trinkets. Every sixth box gets a red ball and every eighth box gets a blue whistle. How often does a box get both a red ball and a blue whistle?

Answer 1

There is about a 3% chance that a box will have a whistle and a ball together.

-the multiples of 6 and 8 are on the same number only once out of thirty ( out of thirty, 24 is the only number with factors 6 and 8) .
-When you do simple math to find out the percentage, you get 3%.

1/30 = (about) 3/100
