Question

13)
Find the probability that a number selected at random from 1 to 40 is divisible by either 4 or 6.
A)1/10
B) 5/10
C)2/10
D) 3/10​

Answer 1

Answer:

bro I will be 13/40

Explanation:

because the multiple of 4 and 6 between 1 to 40 are 13 without repeating the number again

Answer 2

The probability of getting a number divisible by 4 or 6 is 7/20.

Given,

A random number is selected from 1 to 40.

To Find,

The probability that the selected number is divisible by either 4 or 6.

Solution,

The formula for calculating the probability of an event is

Probability = Favorable outcomes/Total number of outcomes.

Here,

Favorable outcomes = 14 {4, 6, 8, 12, 16, 18, 20, 24, 28, 30, 32, 34, 36, 40}

Total outcomes = 40

So,

Probability of getting a number divisible by 4 or 6 = 14/40 = 7/20

Hence, the probability of getting a number divisible by 4 or 6 is 7/20.
