    The expected number of times is (3/4)*16=12 (probability it lands in the
    shaded region times the number of spins)

    2.} John flicks a spinner 50 times. He records the result of each spin in the table below. Which spinner did john most likely spin

    spinner lands on shaded 12 times spinner lands on white 38 times
    In the absence of other information the shaded region has a maximum
    likelihood fractional area of 12/50=6/25.
