A place kicker in pro foot ball has a 77% probability of making a field goal over 40 yd and each attempted field goal is independent if the kicker made his 1st two but missed his 3rd attempt and is now trying for his 4th field goal of the game to win in overtime what is the probability that his team will win the game
A poker player has either good luck or bad luck each time she plays poker. She notices that if she has good luck one time, then she has good luck the next time with probability 0.2 and if she has bad luck one time, then she has good luck the next time with probability 0.4. What fraction of the time in the long run does the poker player have good luck?

Miss 'X' is fond of seeing films. The probability that she sees a film on the day before the test is 0.7. Miss X is any way good at studies. The probability that she maxes the test is 0.3 if she sees the film on the day before the test and the corresponding probability is 0.8 if she does not see the film. If Miss 'X' maxed the test, find the probability that she saw the film on the day before the test.
