Asked by Jillian

A fair number cube, numbered 1 though 6 is rolled 200 times. About how many times can it be expected to on the number 4?

I tried to do 200 divided by 6 which is 33.3333333333 and then I did 100 divided by 6, so then I tried to use a ratio, but I could find one.

prob(getting a 4 ) = 1/6

so in 200 tries, number of times a 4 should show up
= (1/6)(200) = 33 1/3

It said "about" how many times, so I would say
about 33 times
