    Answer:

    A coin is tossed 400 times,

    (i) Number of times Heads is the outcome =280

    Probability of getting a head, P(H)=

    400

    280

    =

    10

    7

    =0.7

    (ii) Number of times Tails is the outcome =120

    Probability of getting a tails, P(T)=

    400

    120

    =

    10

    3

    =0.3

    (iii)P(H)+P(T)=0.7+0.3=1
