Please could someone double check to see if I have correctly answered the question below?
Question:A game involves two dice. One die is normal (numbered one to six), the other die is numbered with the first six prime numbers (2,3,5,7,11,13). Draw a two-way table to illustrate all the possible totals when both dice are thrown.
(a). Probability of the total which is an even number: P (even) = 18/36 = 1/2.
(b). Probability of the total which is less than 12: P = (less than 12) = 22/36 = 11/18.
(c). Probability of the total which is a prime number: P = (prime number) = 13/36.
