## Homework Statement

probability to achieve a couple of 6 launching a couple of dies for 24 times

## Homework Equations

why i cannot calculate this as:

1/36 * (35/36)EXP23 * (24!/23!)

## The Attempt at a Solution

it should be correct:

a="to achive a couple of 6 in 1 throw"

e="never achive a coule of 6 in 24 throws"

i can calculare p(a)=1/36

i can calculate p(e)=[1-p(a)]EXP24

so 1-p(e) should be my correct result
