Question

Q.No.3 A bag contains 16 cards bearing number 1, 2, 3, 16 respectively, one
card is drawn at random. What is the probability that a number is divisible by 3?​

Answer 1

Answer:

Total number of cards = 16

Chances of drawing a numbered card which is divisible by 3 = 5 (They are 3,6,9,12,15)

Probability P() =

Probability of drawing a numbered cards which is divisible by 3

P(card divisible by 3) =

Total cards which are divisible by 3 / Total number of cards

= 5/16

Answer 2

Answer:

no. of cards= 16

types of cards = 4

no. of each type of card = 4
