Simplifying that expression will be
32m + 56mp = 8m (4 + 7p)
You can do that using +6 and -6 .
(6) · (-6) = - 36
(6) + (-6) = 0
The probability of choosing Joey first is 1/12 .
If that happens, the probability of choosing Chloe next is 1/11 .
Then, the probability of choosing Zoe after that is 1/10 .
The probability of all these things happening is
(1/12) x (1/11) x (1/10)
= 1/1320 = 0.00076 = 0.076 percent
