# Help with a probability maths question?

When all of Saphron’s team players turn up for their twice-weekly netball training the chance that they then win their Saturday game is 0.65. If not all players are at the training session then the chance of winning their Saturday game is 0.40. Over a four week period, Saphron’s players all turn up for training three times.

a. Using a tree diagram, with T to represent all players training and W to represent a win, represent the winning chance of Saphron’s netball team. b. Using the tree diagram constructed in part a, determine the probability of Saphron’s team winning their Saturday game. Write your answer correct to 4 decimal places. c. Determine the exact probability that Saphron’s team did not train given that they won their Saturday game.

Any help is much appreciated! :D
