Step-by-step explanation:
24 / (4 x 2 - 5)
PEMDAS
P: Parenthesis = (4 x 2 - 5)
E: Exponents: None
M: Multiplication = (4 x 2 - 5) = (8 - 5)
D: Division = Not yet, because the Parenthesis is not done.
A: Adding = None
S: Subtracting = (8 - 5) = 3
Divide = 24/3 = 8
Total boys = 10 + 7 +10 + 9 = 36
Probability of picking a senior = 9/36 , reduces to 1/4
Total girls = 8 + 11 + 9 + 7 = 35
Probability of picking a senior = 7/35, reduces to 1/5
Probability of picking both multiply the probability of each by each other:
= 1/4 x 1/5 = 1/20
Answer is D.
