Question

A no. is selected at random from the no. 1 to 20. The probability that the selected no. divisible by 3​

Answer 1

Step-by-step explanation:

Numbers that are divisible by 3 or Number of favourable outcomes = 3, 6, 9, 12, 15, 18 = 6

Total number of outcomes = 20 (1 to 20)

P (no. divisible by 3) = Number of favourable outcomes/Total number of outcomes

= 6/20 = 3/10

= 0.3
