If f(x)=4^x-1+6 and g(x)=2x-5, what is (f-g)(x)? a. (f-g)(x)=4^x-1-2x-1 b. (f-g)(x)=4^x-1-2x+11 c. (f-g)(x)=4^x-1-2x-11 d. (f-g)(x)=4^x-1-2x+1

B is correct.

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
