(i) an even number (ii) a perfect number (iii) Multiple of both 2 and 5​

Answer 1

Answer:

(i) 1/2

(ii)1/10

(iii)1/10

Step-by-step explanation:

(i) an even number

in 1-100, there are 50 even numbers.

so, probability = 50/100 = 1/2

(ii) a perfect number

there are 10 perfect numbers - 1,4,9,25,36,49,64,81,100

probability = 10/100= 1/10

(iii) multiple of 2&5

these numbers are 10,20,30,40,50,60,70,80,90,100

so, probability is= 10/100 =1/10
