If two coins are tossed, what will be the probability of getting two tails?

Here, the sample space when two coins are tossed = {(H,T)(H,H)(T,H)(T,T)}

i.e., the total number of outcomes = 4

the event of getting two tails = {(T,T)}

i.e., the total number of favourable outcomes = 1

 Probability of getting the occurrence of an event = $\frac{total no.of favourable outcomes}{total number of outcomes}$

Hence, the probability of getting two tails, when two coins are tossed is$\frac{1}{4}$.
