Suppose that you deposit money into a savings account that receives 5% interest per year on the amount of money that
is in the account for that year.
Assume that you deposit $400 into the account initially.
Determine, to the nearest year, how long it will take for the
initial investment of $400 to double.
Write the number of years in the blank.
Type your answer as a number only, no letters or spaces or
other characters.

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
