part c work out the probability that there are no 6s then subtract from 1

i know how to do first one yes also part c i just checked answer it says 671/1296
deletedabout 10 years
the answer to c is 1 - 625/1296

first one is basically
1/6 x 1/6 x 1/6 x 1/6 x 1/6 x 1/6

You multiply by 4 because any one of the four dice could show up with a 6, so there are a total of four cases

i got the first bit (125/1296) but why do you have to divide by 4 afterwards
deletedabout 10 years
It's actually 125/1296 * 4 which is 125/324
deletedabout 10 years
i have the answer it's 125/324 i just don't know how to do it

no i also feel really stupid for asking
