High school seniors were randomly selected for a survey to determine the location of their class trip. The two choices were an amusement park or an aquarium. The amusement park was the choice of 28 girls and 34 boys. The aquarius was the choice of 9 girls and 8 boys. Create a two-way frequency table for the data, and tinf the probability that a high school senior chose the aquarium. Round to two decimal places.

because its not ur topic and its not for is for homework not that.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

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

nope.   happens to me as well.
