Answer 1

Answer:

Step-by-step explanation:

No.of possible no. that can be chosen=20

No. Of possible multiple of 4=5

(4,8,12,16,20)

Required Probability=5/20. =0.25

Answer 2

The probability that this number will be multiple of 4 is $\dfrac{1}{4}$ .

Explanation:

The multiples of 4 out of first 20 natural numbers = 4 , 8 , 12 , 16  , 20

i.e. Number of multiples of 4 out of first 20 natural numbers = 5

Total numbers = 20

Then, the probability that this number will be multiple of 4 :

$\dfrac{\text{Number of multiples of 4 }}{\text{Total numbers }}$

$=\dfrac{5}{20}=\dfrac{1}{4}$

Therefore , the required probability =$\dfrac{1}{4}$
