Question

three numbers are chosen at random from the first 20 natural numbers the probability that their product is even is​

Answer 1

Answer:

The probability of an event happening is

10/20 = 1/2

Answer 2

Step-by-step explanation:

The product of three randomly chosen integers is even only if each of the three numbers is even. If the three integers are picked WITHOUT REPLACEMENT from the first 20 positive integers, the probability of drawing three even numbers from a pool of the first 20 integers is (10/20) * (9/19) * (8/18) = 270/6840 = 0.03947.
