There are 100 dogs participating in a competition (two from each state)(adsbygoogle = window.adsbygoogle || []).push({});

a. If two dogs are chosen at random, what is the probability they are from the same state?

100/100 x 1/99 = 1/99

b. If a collection of 10 dogs is chosen at random, what is the probability no two are from the same state?

100/100 x 98/99 x 96/98 x 94/97 x 92/96 x... x 82/91

Am I right?

Thanks
