What is the probability that a randomly chosen 2 digit positive integer is a multiple of 3? |
|
Answer» Answer: (a) 2 digit positive integers which are multiples of 3 are 12, 15, 18, ... , 99. Thus, there are 30 such integers. (b) 2-digit positive integers are 10, 11, 12, ... , 99. Thus, there are 90 such numbers. SINCE out of these, 30 numbers are MULTIPLE of 3, THEREFORE, the probability that a randomly chosen positive 2-digit integer is a multiple of 3, is 30/90 = 1/3.Read more on Sarthaks.com - https://www.sarthaks.com/122907/a-how-many-two-digit-positive-integers-are-multiples-of-3 |
