A whole number from 1 to 40 is chosen at random. What is the probability the number is even or a multiple of 3?

The probability that number is even or multiple of 3 between 1 to 40 is

.

Step-by-step explanation:

Consider concept of Probability.

Let, Event A: Number between 1 to 40

The number between 1 to 40 which is even are 2,4, 6, 8,  ... 38,40

Therefore, there are total 20 numbers between 1 to 40 that are even.

Probability that the number between 1 to 40  are even is

  ....(1)

Let, Event B: Number between multiple of 3

& the number between 1 to 40 that are multiple of 3 are  3, 6, 9, ...  36, 39

Therefore, there are total 13 numbers between 1 to 40 that are multiple of 3

To find probability number between 1 to 40 are even and multiple of 3 are

20 + 13 = 33

Now, Probability that number between 1 to 40 are

  1.  even

  2. multiple of 3
