Answer with explanation:
→When a coin is tossed n, times
Total Possible outcome [tex]=2^n[/tex]
→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
[tex]=\frac{\text{Total favorable outcome}}{\text{Total possible outcome}}[/tex]
→Probability of obtaining n' heads in a row when flipping a coin n times
[tex]=\frac{1}{2^{n}}[/tex]
→Probability of obtaining two heads in a row when flipping a coin two times
[tex]=\frac{1}{4}[/tex]
