2. [A3] Two ladders are leaned against a wall so that they make the same angle with the ground. The
taller ladder is 18 feet long. The shorter ladder is 10 feet long. The 10-foot ladder reaches 8 feet up
the wall. How much further up the wall does the 18-foot ladder reach? Label the diagram. Use
similar triangles to solve.

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
