Paul's skateboarding competition will start at 11:30 a. m., but the competitors must arrive at the skate park three-quarters of an hour early to warm up. The
competition must end by 1:30 p. m.
Paul says he has to be at the skate park at 9:30 a. m. Is Paul correct? Explain
your answer.

hi there!

the answer will be d: 2

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

f(x)=2/3x-8, which give g(x) the greatest value.
