Answer 1

Answer:

Step-by-step explanation: THERE ARE 25 NUMBER BETWEEN 1 TO 100

SO THE PROBABILITY IS 1/4

Answer 2

The probability that a number selected at random from 1 to 100 is a prime number​ is 0.25.

Step-by-step explanation:

To find : The probability that a number selected at random from 1 to 100 is a prime number​ ?

Solution :

The prime numbers from 1 to 100 are

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

Favorable outcome = 25

Total number of outcome = 100

Probability is given by,

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total outcome}}$

$P=\frac{25}{100}$

$P=0.25$

Therefore, the probability that a number selected at random from 1 to 100 is a prime number​ is 0.25.
