Question

In a box 25 cards are there and 1 to 25 numbers are written on them. one card is drawn randomly. what is the probability that it is multiple of 5.​​

Answer 1

Explanation :

Given that:

• In a box 25 cards are there and 1 to 25 numbers are written on them.

• • One card is drawn randomly.

To Find:

• • What is the probability that it is multiple of 5.

We know that:

P(E)= F/T

Where,

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

We have:

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

• P(E)= 5/25

• P(E)=1/5

Hence,

The probability that it is multiple of 5 is ⅕
