When solving -1/8(x+35)=-7, what is the correct sequence of operations?

-1 /8 x (x + 35) = -7

- (x + 35) / 8 = -7

(-x - 35) / 8 = -7

-x-35/8 = -7

-x-35 = -7 x 8

-x-35 = -56

-x = -56 + 35

-x = -21

x= 21

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
