Give the probability in decimal form (correct to two decimal places)

A  professor gave 20 As out of 190 grades. If one of the professor's students from last semester were selected randomly, what is the probability that student received an A?

Dec 3rd, 2014

the probability that student received an A = 20/190

                                                                    = 2/19

probability of an event = favourable events/total number of events
