What is the probability of selecting a prime number from 1,2,3,4,5,6,7 ?
Given :
Given numbers are 1,2,3,4,5,6,7.
To find :
We have to find the probability of selecting a prime number.
Solution :
Total number of numbers = 7
Prime numbers among the given numbers are 2,3,5,7
Number of prime numbers = 4
Therefore,
Probability of selecting a prime number from 1,2,3,4,5,6,7 $= \frac{Number \ of \ prime \ numbers}{Total \ number \ of numbers}$
$ = \frac{4}{7}$.
Probability of selecting a prime number from 1,2,3,4,5,6,7 is $\frac{4}{7}$.
