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) $\frac{3}{5}$
Solution:
(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, $\mathrm{P}_{\text {(getting a number less than 4) }}=\frac{3}{8}$
