Question

1.) The probability of rolling a 1 is 1/6. So if the die is rolled 60 times what is the expected number of times you would get a 1. 10 times is the expected value. If the die was rolled hundreds of times and the number of times a 1 came up was recorded the quotient (number of 1s)/(number of rolls) will come closer and closer to 1/6.

2.) For any roll, the probability of getting a 1 is 1/6, so for 60 rolls, the expected number of 1's is 60 x 1/6 = 10. So the result he got was slightly above what would be expected.
