The speed of Gabs tennis serves are normally distributed wit

The speed of Gab\'s tennis serves are normally distributed with a mean speed of 102km h^+1. The probability that Gab\'s serve reaches a speed in excess of 114 km h^-1 is 0.08 Find the probability that Gab\'s next serve is less than 114 km h^-1 Gab records a serve reaching a speed of a km h^-1. If there is a chance of 0 08 that Gab\'s serves teaches a speed of under a km h^-1, find the value of a During a training session Gab practice her serves 150 times. On how many occasions will you expect Gab\'s serve reach a speed of between 102 km h^-1 and 114 km h^-1?
