We know that

Probability of occurrence of an event

= \(\frac{Total\,no.of\,Desired\,outcomes}{Total\,no.of\,outcomes}\)

Total outcomes of the coin are tails and heads

Hence the total no. of outcomes are 2 (i.e. heads and tails)

And the desired output is tail.

Hence no. of desired outcomes = 1

Therefore, the probability of getting a tail is

= \(\frac{1}{2}\)

**Conclusion: **Probability of getting a tail when a coin is flipped is 0.5 or \(\frac{1}{2}\)

Correct Answer – `1/2`
