Question

What is the sample of the following?

A. Roll a six sided die and record the result

B. Roll 2 four sided die and record the sum

Answer 1

Solution:-

A) The sample size is 6.

The sample for a six sided die = 1, 2, 3, 4, 5, 6

B) The sample for the sum is 2, 3, 4, 5, 6, 7, 8. The sample size is 7.

Total number of outcomes is:-

(1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4), (4, 1), (4, 2), (4, 3), (4, 4),

The sample for the sum is 2(1 + 1), 3, (1 + 2) , 4(1 + 3), 5(2 + 3), 6(2 + 4) , 7(3 + 4), 8(4 + 4)  

The sample for the sum is 2, 3, 4, 5, 6, 7, 8.
