Question

if the first positive 200 integers what is the probability when it is divisible by 10​

Answer 1

Integers which are divisible by 6 only

= 200 / 6

= 33 2/6

Take round off value 33

Integers which are divisible by 8 only

= 200 / 8

= 25

LCM. Of 6 & 8 = 24 (numbers divisible by both 6 & 8)

Integers divisible by 24

200 / 24

= 8 8/24

Take round off = 8

Now p(E) = (33 + 25 - 8) / 200

= 50 / 200

= 1 / 4
