Answer with explanation:

→When a coin is tossed n, times

Total Possible outcome
=2^n

→When a coin is tossed twice ,

Total Possible outcome =2²=4={ HH, TT, HT, TH}

→Total favorable outcome , that is getting 2 heads continuously=1

or , Total favorable outcome , that is getting 2 heads continuously=1

→Probability of an event

$=\frac{\text{Total favorable outcome}}{\text{Total possible outcome}}$

→Probability of obtaining n' heads in a row when flipping a coin n times

=(1)/(2^(n))

→Probability of obtaining two heads in a row when flipping a coin two times

=(1)/(4)
