If two DVDs are chosen randomly one at a time, where the first DVD is replaced before the second DVD is chosen, what is the theoretical probability that both DVDs chosen are from the comedy category?

Answer 1

So there are 30 total DVD's

and 10 are in the comedy section

thats a 10/30 chance of pulling 1
or 1/3 when simplified.....

since the DVD is replaced before another is chosen...the probability doesn't change....its still 10/30 or 1/3

so the chance of that happening is 1/3 all the time for the comedy DVD's

Answer 2

its not on there

Answer 3

What are the choices?
