Question

Pick a number from the following list 1,2,3,4 write it down if each student in a class of 50 we’re also to pick a number how many would you guess had selected the same number as you did

Answer 1

13 students

Explanation:

We have a list of four numbers: 1, 2, 3, 4. If 50 persons were to pick a number randomly, it means that the probability of picking any of the numbers is 0.25.

Therefore, from 50 students, 0.25*50 = 12.5 ≈ 13 students aproximately would choose the same number as I did.
