You are told that you will have to wait for 5 hours in a line with a group of other people.  1. You know the number of minutes you have to wait?

2.You know how many people have to wait?

 if you answer yes draw an input-output diagram and write a statement that describes the way one quantity depends on another.

If you answer no give an example of 2 outputs that are possible for the same input.

answer: 20

step-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
