We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
Well, first find out what 20% of $15 is.
20% x $15 = $3
Take that from the original price.
$15-$3=$12
7 1/5 = 36/5
6 2/5 = 32/5
36/5 - 32/5 = 4/5
a. 4/5
We factor out primes from 32 to find it's prime factorization.
32=2*16=2*2*8=2*2*2*4=2*2*2*2*2. 2 is a prime number, so this cannot be reduced further. Since we have five twos and no other primes, the factorization is 2^5, and the only prime factor is 2.
Answer:
(1) P(A) + P(B) - P(AB)
