At some distance away, at an elevation of 15,072 feet above sea level, Thomas Montgomerie recorded an angle of elevation to the top of the 2nd peak he observed in the Karakoram range (K2) to be 1.144º. From the same elevation but 5 miles closer, he records the angle of elevation to the summit of K2 to be 1.1910. (a) Based on his calculations, how high above sea level (in feet) is the summit of K2?

you would need to know all the numbers that are on there

step-by-step explanation:

85.560%

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

answer: i think it is c
