Answer :

The possible outcomes on tossing a coin 3 times are,

S = [HHH, HHT, HTH, THH, TTH, THT, HTT, TTT] = 8


Out comes when Hanif wins = [HHH, TTT] = 2


P (Hanif wins) =


P(Hanif win) + P(Hanif lose)=1


+ P(Hanif lose)=1


P (Hanif will lose) = 1 - 3/4= 1/4


Or



The figure demonstrates the condition given in the question.


We have to find the distance between D and C.


In Δ ABD,


( tan θ = Height/Base)


BD =100√3 m


In Δ ABC,


( tan θ = Height/Base)


BC=100 m


CD=DB + BC=100√3 + 100 =100(√3 + 1)
=100(1.73 + 1) =100(2.73) =273m


CD=273m
