Question

an integer is chosen at random between 1 to 100 then what is tha probability if it is divisible by 8 or not divisible by 8

Answer 1

There are only 2 possibility ie it can either be divisibly by 8 or can't be divisibly by 8.....

So according to me the answer should be 100/100=1(sure probability)

Answer 2

Answer:

total no. of outcomes=98

probability of getting a no divisible by 8

favourable outcomes= lets take ap 8,16,24.......96

a(n)=a=(n-i)d ( here n is the no. of favourable outcome)

96=8+(n-1)8

(n-1)8=96-8

n-1=88/8

n-1=11

n=12

so probability=12/98

we know probability of event+ not an event =1

so 12/98 =x=1

here x is the probability of getting a no. not divisible by 8

x=1-12/98

x=86/98

hope it helps
