Question

If three different coins are tossed together, then what is the probability of getting two heads?

Answer 1

Find the probability of getting two heads

Possible outcomes when three coins are tossed together : $\left\{HHH,HTH,THH,TTH,HHT,HTT,THT,TTT\right\}$
Total number of outcomes $=8$
Number of favorable outcomes of exactly two heads $=3$
Probability of an event $=\frac{Favorableoutcomes}{Totaloutcomes}$
Probability of getting two heads $=\frac{3}{8}$

Hence, the required probability is $\frac{3}{8}$
