99 points for his phone service, charlie pays a monthly fee of $ 18 , and he pays an additional $ 0.06 per minute of use. the least he has been charged in a month is $ 102.24 . what are the possible numbers of minutes he has used his phone in a month? use m for the number of minutes, and solve your inequality for m .

m - the number of minutes

The inequality:

greater than or equal to 1404.

stethere all not eveanp-by-step explanation:

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
