Question

Tick (✓) the correct answer:
Two coins are tossed simultaneously. What is the probability of getting one head and one tail?
(a) $\frac{1}{4}$
(b) $\frac{1}{2}$
(c) $\frac{3}{4}$
(d) $\frac{2}{3}$

Answer 1

(b) $\frac{1}{2}$

When two coins are tossed, the possible outcomes are HH, HT, TH and TT.
​Total number of outcomes $=4$
Number of outcomes with one head and one tail $=2$
$\mathrm{Now},{\mathrm{P}}_{\left(\mathrm{one}\mathrm{head}\mathrm{and}\mathrm{one}\mathrm{tail}\right)}=\frac{2}{4}=\frac{1}{2}$
