Answer:
Probability = 7/8
Step-by-step explanation:
n(sample space) =200
25 numbers out these 200 are divisible by 8,those are 8,16,24,32,40,48,56,64,72,80,68,96,104,112,120,128,136,144,152,160,168,176, 184,192 and 200.
so the numbers not divisible by 8 will be excluding these 25,
No of number not divisible by 8 =200-25 = 175
Probability that the number chosen between 1 to 200 is not divisible by 8
=175/200
=7/8
=0.875 (writing answer in decimal is not required)
