In a school of 1250 students, 250 are freshmen and 150 students take spanish. the probability that a student takes spanish given that he/she is a freshman is 30%. what is the probability that a randomly selected student is a freshman given that he/she takes spanish?

The answer is C. 50%

Step-by-step explanation:

Let F = freshman and S = Spanish student.

P(F) =  250 /1250  = 20%

P(S) =  150 /1250  = 12%

P(S|F) =  P(S∩F) /250  = 30%

⇒ P(S∩F) = 250 · 30% = 75

P(F|S) =  P(S∩F) /150  =  75 /150  = 50%

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
