A coin is tossed once. Find the probability of getting a tail.

Answer»

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  \(\frac{1}{2}\)
