Several trusses are needed to build the frame of the shed roof. Each roof truss is 16 inches apart, as measured from the centers of the beam widths.
The roof could be constructed so that the ridgeline of the roof is parallel to the longest dimension of the shed (first
picture below) or it could be constructed so that the ridgeline of the roof is parallel to the shortest dimension of the
shed (second picture below).

Calculate how many roof trusses would be needed to frame the roof if the ridgeline runs parallel to the longest side of
the shed. Enter this number in the response box.

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
