Question

Francis and Gary agree to meet at the monkey bars for a swinging contest sometime during their half-hour recess. If each of them shows up at the monkey bars at a random time during recess and each will only wait five minutes for the other before leaving, what is the probability that they meet at the monkey bars. I solved the problem using geomertric probability but I need to solve it by using conditional probability

Answer 1

graph \(|x-y|=5\) on the interval \((0,30)\) and use areas

Answer 2

i know of no other way to do the problem, geometric, conditional or otherwise

Answer 3

Yes, that's what I got. Answer 11/36. But there is another way to solve it, I just can't figure the probabilities
