What is the probability that a randomly chosen natural number between 30 and 39 is divisible by three?

Let’s calculate the number of numbers from 30 to 39: 39 – 30 + 1 = 10 numbers.

Of these, they are divided into three following: 30, 33, 36 and 39 (four numbers in total).

Therefore, the probability that the number is divisible by 3 is 4/10 = 0.4.

Answer: The probability that a randomly chosen natural number between 30 and 39 is divisible by three is 0.4.
