Do you know the distribution property? I can't explain why you have to do that, but google search it. the number that is outside of the parenthesis will be multiplied in <em>each </em>of the number in the parenthesis.
-8(-8b-6) = -6b-22
the distribution property will look like this
-8 * -8b = 64b
-8 * -6 = 48
(two negative numbers make a positive)
now th equation will look like this
64b + 48 = -6b-22
you must have the variable to one side of the equation. That means you need to subtract one of them to the other side or add it depending if the number is positive or negative. For example, you can add 6b to 64b (the opposite operation of -6b is addtion making -6b a positive number) so 64b + 6b - 70b
70b + 48 = -22
solve b!

Answer:
1820
Step-by-step explanation:
X the size of the club will follow negative binomial distribution with probability of success p and number of failures r
p = 364/365, r = 5
hence E[x] = pr/(1-p) = 364/365 x 5 /(1/365) = 1820
