Hey all,

I was going over some questions in my textbook when I came across these two questions. I could not get the answer in the back of the book (possibly because there is an error) or I did something wrong. I'd appreciate it if anybody can help me out.

1) If the odds in favor of team A winning the championship is 1:5, and the odds in favor of team B winning the championship is 2:13, what are the odds in favor of either team A or team B winning the championship.

2) What is the probability that exactly two out of eight friends will have the same birthday?


I'd appreciate any input

Thanks
