The probability a tennis player gets her first serve in court is 60%. If she gets her first serve in court the probability of winning the point is 80%. The chance of getting her second serve in court is 75% and if she gets her second serve in court the chance of winning the point is 60%. If the tennis player fails to get her second serve in court she loses the point.
Draw a tree diagram to show this information.
Find the probability of the tennis player winning the point if she fails to get her first serve in court.
Hence find the probability of the tennis player winning the point.
