Question

Tick (✓) the correct answer:
8 cards are numbered as 1, 2, 3, 4, 5, 6, 7, 8 respectively. They are kept in a box and mixed thoroughly. One card is chosen at random. What is the probability of getting a number less than 4?
(a) $\frac{1}{2}$
(b) $\frac{3}{4}$
(c) $\frac{3}{8}$
(d) $\frac{3}{5}$

Answer 1

(c) $\frac{3}{8}$

Total number of cards $=8$
Number of cards with numbers less than 4 $=3$ (cards with numbers 1, 2 and 3)
Now, ${\mathrm{P}}_{\left(\mathrm{getting}\mathrm{a}\mathrm{number}\mathrm{less}\mathrm{than}4\right)}=\frac{3}{8}$
