Question 7 • Algebra 2 with Probability

For students majoring in Hospitality Management, it was determined that 5 percent have visited 1 – 10 states, 16 percent have visited 11 – 20 states, 45 percent have visited 21 – 30 states, 19 percent have visited 31 – 40 states, and 15 percent have visited 41 – 50 states. Suppose a Hospitality Management student is picked at random. What is the probability that the student has not visited between 21 and 30 states?

Answer
A
0 point 2 1
B
0 point 5 5
C
0 point 4 5
D
0 point 3 4

Explanation

The probability that a student has visited 21–30 states is 45%, or 0.45. The probability of not being in that group is its complement: 1 − 0.45 = 0.55. Therefore, the answer is 0.55, choice B.
