Question

Please explain how to get the answer.I have now idea.

1.If you roll two fair dice,one red and one green,what is the probability of getting a 2 on the red die and a 3 on the green die? Give answer in a reduced fraction.

2.If you roll two fair dice,one red and one green,what is the probability that the sum of the two dice is 5? Give answer in a reduced fraction.

3.If you roll two fair dice,one red and one green,what is the probability of getting a leat one 6 on the two dice?Give answer in a reduced fraction.

Answer 1

1. prob = (1/6)(1/6) = 1/36

2. the colour does not matter
there are 4 ways to get a sum of 5
(1,4) (2,3) (3,2) (4,1)
prob = 4/36 = 1/9

3. Again, what does the colour have to do with it?
prog(no 6 showing) = (5/6)(5/6) = 25/36
prob(at least one 6) = 1 - 25/36 = 11/36

Answer 2

Find P(1 on green die and 3 on red die). (Enter your answer as a fraction.)
