Question

If two coins are tossed then find the probability of the events that at the most one tail turns up

• A. $\frac{1}{4}$
• B. $\frac{1}{3}$
• C. $\frac{1}{2}$
• D. $\frac{3}{4}$

Answer 1

Answer: (D)

$\frac{3}{4}$

The sample space of 2 coins tossed $=(h,h),(h,t),(t,h),(t,t)$
for having atmost one tail we need$=(h,t),(t,h),(h,h)$
Thus the probability is $\frac{3}{4}$
