Question

Two coins are tossed together. What is the probability of getting at least one tail

Answer 1

The possible outcomes when two coins are tossed together are {$HH,TT,HT,TH$}. Therefore, the number of possible outcomes when two coins are tossed is $4$.

Now, the possible outcomes of getting at least one tail are {$TT,HT,TH$}, which means the number of favourable outcome is $3$.

Therefore, probability $P$ of getting at least one tail is:

$P=\frac{3}{4}$

Hence, the probability of getting at least one tail is $\frac{3}{4}$.
