One of the construction workers likes to listen to music on the job. Unfortunately, he also has a bad habit of accidentally dropping his music player into the ravine! Luckily, his daughter is good with physics and has built a safety balloon for his latest music player that will release after the music player has been falling for 1 second. Where t is the amount of time since the construction worker dropped his music player. Will the balloon release in time?

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
