Question
Two different coins are tossed simultaneously .Find the probability of getting :
(ii)no tail
(ii)no tail
✓
Answer
Possible outcomes for tossing two coins are: $\mathrm{HH}, \mathrm{HT}, \mathrm{TH}, \mathrm{TT}$ So the number of outcomes $=4$
favorable outcomes are: $\mathrm{HH}$
So, $P($ No tail $)=\frac{1}{4}$
favorable outcomes are: $\mathrm{HH}$
So, $P($ No tail $)=\frac{1}{4}$
