Question

From first 50 natural numbers, a number is selected. What is the probability that the number is a multiple of 6 or 15?​

Answer 1

Answer:

Total number of Outcomes = 50

Favourable outcomes of getting multiple of 6 and 15=

Multiples of 6= 6, 12, 18, 24, 30, 36, 42, 48, 54=8

Multiples of 15= 15, 30, 45=3

P(x) = Favourable outcomes / Total outcomes

P(getting multiple of 3 and 5) =>

=8+3=11

=11/50 is the probability of getting the number as a multiple of 6 or 15

Answer 2

The probability of number is a multiple of 6 or 15 is 1/5.

Definition of probability.

Probability is a metric for determining the possibility of an event occurring. Many things are impossible to forecast with 100% accuracy. Using it, we can only anticipate the probability of an event occurring, i.e. how probable it is to occur.

According to the question:

Multiples of 6 are 6,12,18,24,30,36,42,48.

Multiples of 15 are 15,30,45.

Common term is 30.

Probability of 6multiples is 8/50

Probability of 15multiples is 3/50

Probability of common term is 1/50

So, required probability is, 8/50+3/50-1/50

=10/50

=1/5

Hence, A number that is a multiple of 6 or 15 has a probability of 1/5.
