Please help.

On Alan's first visit to Macau, he decided to try his luck in at the Venetian Casino Resort. He played a game that is supposed to offer a 40% chance of winning. Out of five independent plays, he won the first 4 games and lost the last game. His friend Brad suspects that the game is rigged in Alan's favour and decides to carry out a hypothesis test. (a) State Brad's null and alternative hypotheses. (b) If the null hypothesis is true, what is the chance of winning 4 games in a row and losing the next one? (c) Calculate the P value based on Alan's data, to one significant figure. (d) What can Brad conclude, based on 5% level of statistical significance
