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 randomly selected. What is the probability that the student has visited 21 or more states?
