Question

1) Find the probability of rolling at least one 6 2)Find the probability of rolling exactly one 6

Answer 1

For item 14: 1/36 (there is only one possible way of having both dice as 3)

For item 15: 1/18 (because there are 2 ways that one is 5 and one is 6 so it is 2/36 or 1/18)

For Item 16: 5/9 (because there 20 ways we can have a 5 or 6. 20/36)

For item 17: 11/36 (because there are 11 ways of having at least one six)

For item 18: 25/36 (because there are 25 ways having numbers other than 6)

For item 19: 5/18 (because there are 10 ways having exactly one six 10/36)
