Question

Suppose we want to pick two numbers from 1 to 100 find probability that sum of two numbers is multiple of 5

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The probability that sum of two numbers is multiple of 5 is $\frac{1}{5}$

Solution:

The probability of an event is given as:

$Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}$

we want to pick two numbers from 1 to 100

Thus,

Total number of possible outcomes = 100

Favorable outcomes = sum of two numbers is multiple of 5

Favorable outcomes = 20

Therefore,

$Probability = \frac{20}{100}\\\\Probability = \frac{1}{5}$

Thus the probability that sum of two numbers is multiple of 5 is $\frac{1}{5}$
