    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
