Question

Find the probability that a natural number selected at random from 1 to 10 is a

prime number.​

Answer 1

Answer:

2/5

Step-by-step explanation:

prime numbers from 1 to 10 = {2,3,5,7}

probability = no. of digits/total digits

hence, probability = 4/10

i.e.=2/5

Answer 2

Answer : 2 / 5

Explanation :

No of possible outcomes = 10

No of possible outcomes = 10 Let ' R ' be the event of getting random natural prime number from 1 to 100

No of possible outcomes = 10 Let ' R ' be the event of getting random natural prime number from 1 to 100 Number of favourable outcomes of P (R) = (2,3,5,7) = 4

P (R) = Number of outcomes favourable to E / Number of all possible outcomes of the experiment

P (R) = 4/10 = 2/5
