Question

find the chance of picking an even numbers from the series of natural numbers 1 to 100:
A) 1/100
B) 1/50
C) 1/2
D) None of these​

Answer 1

Answer:

1/2

Step-by-step explanation:

Total no. of natural nos. = 100

no. of even natural nos. = 50

Probability of getting even no. from the lot = 50/100

= 1/2

Answer 2

Answer:

Option C is correct.

Step-by-step explanation:

Question:

find the chance of picking even numbers from the series of natural numbers 1 to 100.

Let us consider a series with even numbers from 1 - 100.

                    2,4,6,8,10,…..,98,100

The above series is an arithmetic progression(A.P)., a=2, d=2, tn=100

tn = a+ ( n-1 ) d

=> 100 = 2 + (n-1) x 2

=> n-1 = 49

Therefore, There are 50 even numbers between 1 to 100.

The probability of getting an even number from the series of natural no.s = $\frac{50}{100}$  = $\frac{1}{2}$.

Hence, Option C is correct.
