Question

A student argues that there are 11 possible outcomes (sum of numbers on both dice) 2,3,4,5,6,7,8,9,10,11 and 12 when we throws two dice simultaneously. Therefore each of them has a probability 111. Do you agree with this argument? Justify your answer.

Solution


Event:Sum of two dice 2 3 4 5 6 7 8 910 11 12
Probability 136 236=118 336=112436=19 536 636=16 536436=19 336=112236=118 136
Total number of outcomes=36
It can be seen that each term does not have a probability of 111
, it is an incorrect argument.
