A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%
b.) Probability of selecting three students and one faculty members from 20
students and 5 faculty volunteers = no of ways of selecting three students
and one faculty members from 20 students and 5 faculty volunteers
divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
Answer:
52.09
Step-by-step explanation:
Follow the acronym PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) for order of operations problems.
1. Solve what is in parentheses. (9 - 7) = 2
48 ÷ 23 + 25 (9 - 7) = 48 ÷ 23 + 25 × 2
2. Divide. 48 ÷ 23 = 2.09
2.09 + 25 × 2
3. Multiply. 25 × 2 = 50
2.09 + 50
4. Add. 2.09 + 50 = 52.0
I know that 52.09 wasn't one of the options listed, but it is the exact answer. If you must choose one of those options, choose 50, since it is the closest.
