Question

Find the probability of numbers divisible by 2 or 5 between 0 & 100

Answer 1

Answer:

Number of integers between 0 and 100=99

Number of possible outcomes =99

Let E be the event of getting an integer divisible by 7.

Outcomes favourable to E are 7,14,21,28,35,42,49,56,63,70,77,84,91,98

Number of favourable outcomes =14

P(E)=

Numberofpossibleoutcomes

Numberoffavourableoutcomes

P(E)=14/99

Hence the probability of getting an integer divisible by 7 is 14/99.
