Two number cubes, when rolled,
will produce: To find the expected number of times in 48 rolls, multiply each by 48
a sum of 2, 1/36th of the time x 48 = 48/36 = 1.3333...
a sum of 3, 2/36th of the time x 48 = 96/36 = 2.6666...
a sum of 4, 3/36th of the time x 48 = 144/36 = 4...
a sum of 5, 4/36th of the time x 48 = 192/36 = 5.3333...
a sum of 6, 5/36th of the time x 48 = 240/36 = 6.6666...
a sum of 7, 6/36th of the time x 48 = 288/36 = 8...
a sum of 8, 5/36th of the time x 48 = 240/36 = 6.6666...
a sum of 9, 4/36th of the time x 48 = 192/36 = 5.3333...
a sum of 10, 3/36th of the time x 48 = 144/36 = 4...
a sum of 11, 2/36th of the time x 48 = 96/36 = 2.6666...
a sum of 12, 1/36th of the time x 48 = 48/36 = 1.3333...
Only answer (c) has the exact value
