P(getting a different number on each die) = P(1st roll is ANY number AND 2nd roll is different from 1st roll AND 3rd roll is different from 1st and 2nd rolls)BTGmoderatorDC wrote: ↑Sun Jan 23, 2022 5:22 pmWhat is the probability of rolling three six-sided dice, and getting a different number on each die?

= P(1st roll is ANY number) x P(2nd roll is different from 1st roll) x P(3rd roll is different from 1st and 2nd rolls)
= 6/6 x 5/6 x 4/6
= 5/9
Answer: D
