    Answer:

    93/100

    Step-by-step explanation:

    In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female

    Number of Freshman = 60

    Number of female = 55

    Number of Freshman female 22

    Total number of students = 100

    The probability that a student picked from this group at random is either a freshman or female

    Thus P(freshman or female) = 60/100 + 55/100 – 22/100 = 93/100
