350 high school students are currently enrolled in a French class, a Spanish class, or both French and Spanish classes. 230 students are currently enrolled in a Spanish class. In the first column, identify a possible number of students currently enrolled in a French class. In the second column, identify the corresponding number of students enrolled in both French and Spanish. The two numbers must be consistent with each other. Make exactly one choice in each column. French French AND Spanish Number 140 180 200 220 260 280

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
