Probability help with this question please?

Ok I have a probability question which is making me ill. I have a series of questions. Event 1 is that you have you win a prize 1/15th and the second event you fall over 0.023. I will take a link to any page which will help with this or an answer with workings as I have a few of these to do. Many thank yous, no 'do your own homework' answers thanks.
