Question

an integer is chosen at random between 1 and 100 find the probability that it is divisible by 8

Answer 1

Hey friend..!! here's your answer
_________________________

Integers between 1 and 100 that it is divisible by 8

: 8 , 16 , 24 , 32 , 40 , 48 , 56 , 64 , 72 , 80 , 88 and 96

There are 12 integers which are divisible by 8 between 1 and 100

Number of favourable outcomes = 12
Total Numbers = 100

$P(E) = \frac{number \: of \: favourable \:outcomes }{total}$

$P(Divisble \:by\: 8\: between \:1 \:and\: 100) \: = \frac{8}{100} \\ \\ = \frac{2}{25}$
