3/7, 3/4, 3/5 to greatest to least

3/4 ,3/5,3/7

Step-by-step explanation:

Imagine that your filling up a rectangle cut into parts.

- 3/4 would mean that the rectangle is cut into 4 parts. The top number/numerator is how many part you fill in. So, you only fill in 3 parts. Now you only have 1 part left.

- 3/5 would mean that the rectangle is cut into 5 parts. You are only filling in 3.  Now you have 2 parts left that are not filled in.

-3/7 would mean that the rectangle is cut into 7 parts. You are only filling in 3. Now you have 4 parts left to fill in.

What rectangle had the least amount of parts left? 3/4

Then just put them in order, 3/4,3/5, 3/7

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
