Question

Two tetrahedral dice with faces marked 1,2,3 and 4 are thrown. The score obtained is the sum of the numbers on the bottom face. Tabulate the probability distribution for the score obtained,how?

Answer 1

For a single die, the faces have an equal probability of `1/4`.

For two dice, the probability of each event is `=1/4xx1/4=1/16`

There are `4xx4=16` total possible events.

Explanation:

The tabulation below shows all 16 events and the sums for each event. The possible sums range from 2 through 8 .

For example, the probability that the sum equals 4 is 0.1875 because there are 3 ways to roll a sum of 4. `3 xx 1/16=3/16=0.1875`
