Pls answer correctly! A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results: 80 choose the aquarium.

60 choose the science center.

30 choose the planetarium.

40 choose the farm.
IN total, the whole school has 1000 people

question-Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.

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
