  • Math ASAP please - ,

    in #1 - 3 you don't state what the event is, so those questions are incomplete

    #4. Odds in favour of some event
    = prob of the event / prob of not the event

    prob of correct choice = 1/5

    so the odds in favour of picking the right answer
    = (1/5 / 4/5)
    = 1/4
    or 1 : 4
