    Answer:

    The probability that the student will select a card that has both the same number in the ones place in the tens place is 0.08

    Step-by-step explanation:

    To solve this exercise we have to know that the probability is calculated by dividing the number of favorable events by the number of possible events.

    f = favorable events

    we will count how many numbers between 1 and 50 have the same number in the ones place in the tens place

    11 ; 22 ; 33 ; 44

    as we can see there are 4 numbers

    f = 4

    p = possible events

    the number of possible events is given by the number of cards in the deck

    p = 50

    4/50 = 0.08

    The probability that the student will select a card that has both the same number in the ones place in the tens place is 0.08
