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

Answer:

Probability of drawing a card having a number which is multiple of 5 is 1/5.

Step-by-step explanation:

Since, probability of any event is defined as :

$\frac{number \: of \: favorable \: events \: possible}{total \: number \: of \: events \: possible}$

Therefore here we have :

Number of favorable events possible is 5 and

Total number of events possible is 25.

Hence, probability is 1/5.

Answer 2

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

Finding the probability that it is multiple of 5:

ㅤ↠ㅤP(E) = 5/25

ㅤ↠ㅤP(E) = 1/5

Hence,

• The probability that it is multiple of 5 is 1/5.
