Question

Pablo rolled a standard die 60 times. He got a 1 twelve times. How does this result compare to the expected results? Explain.

Answer 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?

Answer 2

2

Answer 3

The expected number of times you would get a 1 is:
\[60\times \frac{1}{6}=?\]

Answer 4

@Marmar123 Are you there?

Answer 5

and that is 10 right

Answer 6

Yes, 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.
