You have used your trigonometry skills to find the distance from the top of the mountain to base of the mountain located at point C. Now, imagine that you are at the top of the mountain and you notice a restaurant located at point D.
You are curious to know the angle of elevation from point D to Point A.
You are told that the distance between the base of the mountain to the restaurant is approximately 1499 ft.
Find the angle of elevation from point D to Point A

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

wait nvm i know the correct answer now its 100%   81 square feet
