Hi I need help with the following questions with working out please:
Two dice are rolled and the sum of the numbers is calculated:
a) knowing that one of the dice shows six, find the probability that the sum is 11.
b) given that one of the dice shows an even number, find the probability that the sum is 7.
THANK YOU SOOO MUCH
