Jena has a rope that is 4 1/4 inches long. If she divides the rope into sections that are exactly 1/4 inch in length, how many 1/4-inch sections will she have?

17 1/4 inch sections

Step-by-step explanation:

4 1/4 = 4.25

1/4 = .25

Simply do 4.25/.25 to get 17.

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
