Question

What is the probability of obtaining twotwo headsheads in a row when flipping a​ coin? Interpret this probability.

Answer 1

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)`
