How many outcomes are there with 4 dice?
My initial reaction is to say that the answer is 64, since 4 dice can have 6 outcomes.
What is the probability the sum of the four dice equals 7?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
What is the probability of getting a sum of 6 or 4?

How many combinations of 5 dice are there?
5 dice. Now things are getting a little busy! There are 7776 possible combinations for five dice.
What is the probability of getting a sum of 22?
⇒6+6+6+4=22 , this arrangement is possible in 4 ways with different positions of numbers 4 to appear. Hence, the option (B) is the correct answer.
When 4 dice are rolled what is the probability of getting a sum of 16?
When 4 dice are rolled what is the probability of getting a sum of 16? Probability that the sum is 16=6/6*6*6*=1/36.
What is the formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
