Question

8 cards are numbered as 1, 2, 3, 4, 5, 6, 7, 8 respectively. They are kept in a box and mixed thoroughly. Once card is chosen at random. What is the probability of getting a number less than 4? ½ ¾ 3/8 3/5 Select the correct answer from above options

Answer 1

(c) 3/8 We know that the, Total number of cards kept in the box = 8 ∴ number of cards having a number less than 4 on it = 3 By using the formula, Probability p () = number of favorable outcomes/ total number of outcomes ∴ Probability of selecting a card with a number less than 4 on it p(no.of cards less than 4) = number of cards having a number less than 4/total number of cards = 3/8
