Question

what is the probability of the event that a number chosen from 1 to 10 is a prime number ​

Answer 1

Answer :

• 2 : 5 is the Probability

Given :

• The event that a number chosen from 1 to 10 is a prime number

To find :

• Probability

Solution :

Given,

• The event that a number chosen from 1 to 10 is a prime number so,

• Total number is 10
• Prime number is 4

We know that

• Probability = Prime number/Total number

Where,

• Prime number is 4
• Total number is 10

Finding the Probability :

↦ Probability = Prime number/Total number

↦ Probability = 4/10

↦ Probability = 2/5

↦ Probability = 2 : 5

Hence,

2 : 5 is the Probability of the event that a number chosen from 1 to 10 is a prime number.

Answer 2

Answer:

there are 4 prime numbers between 1 and 10.

2,3,5,7

So, probability of the event that a number chosen from 1 to 10 is a prime number = 4/10 = 2/5
