    In simplified fraction, it is expressed as : 1/16, 1/4, 3/8, 1/4, 1/16.

    Step-by-step explanation:

    The discrete probability distribution for the random variable is as follows:

    The number of tails possible in four tosses of a coin are 0,1,2,3,4

    The total number of outcomes are

    The Probability distribution is

    X 0 1 2 3 4

    P (X) 1/16 4/16 6/16 4/16 1/16

    Therefore, In simplified fraction, it is expressed as : 1/16, 1/4, 3/8, 1/4, 1/16.
