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
