The part tripping me up here is do i count the .12 to the entire fan base, or just the .08, because the end of the question gave me that impression.

At a baseball game, the probability that a fan brings a glove is 0.08. The probability that a fan is left-handed is 0.12. What is the probability that a randomly selected fan has a baseball glove and is left-handed?

Take your time ^^

Im pretty positive that you would just add 0.08 and 0.12 together..this is kinda confusing..lol..Do u have choices tho?

anonymous · Answer

I do not :/

Don't mean to interrupt, but the fundamental thereoms of probability state that in a situation like this multiplication is necessary. That is: the probability of finding a lefthanded glove holding fan is the probability of a lefthander times the probability of being a glove holder. Thus, p=.08*.12=.0096.
