I am trying these before I ask for help. I just can’t budge

Step-by-step explanation:

Usually, filling in a two way table is very easy to do. It helps you derive the answer quicker. To do this, we add every first across column and write it in total (14 male) while second across column (16 female.)

Then we add them by row: freshmen are 7 people, sophomores are 10, juniors contain 8 people and seniors are 5.

This problem is asking you out of the freshman being male, find the percentage of it being a freshman. So we go to the total amount of male 14. Next, we find how many males are in the freshman class (4). Divide 4/14 to get 1/7, or 0.14 percent.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

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
