Answer with Step-by-step explanation:
Let
A=Students are female
B=Students major in civil engineering
The probability that a students are female=P(A)=
The probability that a student major in civil engineering=P(B)=
The probability that students both are female=
a.We have to find the probability that a random selected female student major in civil engineering.
We have to find 
Hence, the probability that a randomly selected female student majors in civil engineering=0.24
b.We have to find the probability that a random selected civil engineering major is female.
We have to find 
Hence, the probability that a randomly selected civil engineering major is female=0.63
Answer: 15.75
Step-by-step explanation: To calculate, we do 45 x 35 / 100 which will equal 15.75

Let's make
A = adult tickets sold
C = child tickets sold
A + C = 162
5.90C + 9.50A = 1182.60
if .. A+C = 162 then A = 162 - C
substitute (162 - C) for A in the other equation.
5.9C + 9.5(162-C) = 1182.6
5.9C + 1539 - 9.5C = 1182.6
-3.6C + 1539 = 1182.6
-3.6C = 1182.6 - 1539
-3.6C = -356.4
C = -356.4/-3.6
C = 99 tickets
