Find the average of all prime numbers between 30 and 50

Answered by admin @ 11/08/2021

First, we will write all the prime numbers between 30 and 50

Prime numbers between 30 and 50 are 31, 37, 41, 43, 47

We know that,

Average = $\dfrac{\tt{Sum\:of\:observations}}{\tt{Total\:number\:of\:observations}}$

Sum of observations = 31 + 37 + 41 + 43 + 47 = 199

Total number of observations = 5

Average (A) = $\dfrac{\tt{Sum\:of\:observations}}{\tt{Total\:number\:of\:observations}}$

☛ A = $\dfrac{199}{5}$

☛ A = 39.8

∴ The average is $\large{\boxed{\boxed{\rm{39.8}}}}$
