It is 9: 00 a. m. when the math lesson starts, and it lasts for 55 minutes. what time will it be when the math lesson ends?

Just as a side note (as you do not need it for this question), an hour = 60 minutes, not 100 minutes.

Math lessons start at 9:00 A.M., and lasts for 55 minutes. Add 0:55 to 9:00

9:00 + 0:55 = 9:55

9:55 A.M. is when math lessons end.

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
