A spinner is divided into 5 equal sections numbered 1, 2, 3, 4, and 5. If the spinner is spun and a coin is tossed, what is the probability of getting a tail on the coin and an odd number on the spinner

  • math -

    P(tail) = 1/2
    P(odd) = P(1)+P(3)+P(5) = 1/5+1/5+1/5=3/5

    Joint probability of two independent events
    = P(odd)*P(tail)
    = 3/5*1/2
    = 3/10

  • math -

    P(tail) = 1/2
    P(odd) = P(1)+P(3)+P(5) = 1/5+1/5+1/5=3/5

    = P(odd)*P(tail)
    = 3/5*1/2
    = 3/10
