Answer to Question #290745 in Statistics and Probability for gio

Question

The odds of Matthew doing his math homework is 13:7. What is the probability of Matthew doing his homework once in the next two days?

Answer 1

The odds of an event is a ratio of the probability than an event will occur and the probability that the event will not occur.

Here, the total number of chances is 13+7=20 and the chances of Mathew doing his Math homework is 13. Therefore, the probability that Mathew will do his Math homework is ${13\over 20}$ .
