# Probability problem watch

1. Hi, could somebody please help me with this problem?

During a court case the jury has to decide whether or not an unlikely event has occurred based
upon the testimony of two independent witnesses. Let:-
• τ be the probability of the unlikely event occurring;
• α be the probability witness A tells the truth;
• β be the probability witness B tells the truth.
Given that both witnesses claim that the event occurred:-
(a) What is the probability that the event occurred?

Just a starting point would be great, im not quite sure how to approach it. Probability really isnt my strong point
2. mate you know how to do Q4 lol?
3. Would you use tables?
4. Q4? And i dont think tables would help me
