    Answer:

    a. 0.05 b. 0.95

    Step-by-step explanation:

    The probability of obtaining a graduate over the age of 30 is 5% = 0.05

    a. Out of 100 people, the probability of obtaining 5 university graduates is number of graduates required/total number = 5/100 = 0.05

    b. The likelihood of not being a graduate is 1 – probability of being a graduate = 1 – 0.05 = 0.95
