Question

If two balanced dice are rolled, what is the probability that the sum of the two numbers that appear will be odd?

Answer 1

The sample space for the experiment has a total of  36  possibilities.

Sample space  for an odd sum is { 1,2  1,4  1,6  2,1  2,3  2,5  3,2  3,4 3,6  4,1  4,3  4,5  5,2 ,5,4  5,6  6,1  6,3  6,5 }

Probability = 18/36  = 1/2
