Explain in your own words how to write an equivalent expression in expanded form when given an expression in the form of ( + ). Then, create your own example to show off what you know.

We can write an equivalent expression by expanding the given expression:

Suppose a binomial with the 2 terms being added. We can expand the first term into x+x if the original first term is 2x and so on with the other term(s).

85.560%

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

d is the answer
