@MonKiwi

Answer 7

so there were 4 3s and 6 6s...

great what was the total number of rolls..?

Answer 8

10
I'm not sure over what number though.

Answer 9

add the number of times each outcome occurred...

Answer 10

Oi vey, I mean the number of times 3 and 6 occured is 10..

Answer 11

or... how many rolls made up the experiment

Answer 12

Well, I added up the numbers each occured, and got 40, so I'll assume that's how many rolls.

Answer 13

So would the fraction be 1/4 ?

Answer 14

great so

P(3 or 6) = 10/40

now simplify the fraction

Answer 15

and you are correct
