Question

An integer is chosen at random out of the integers from 1 to 100. What is the probability

that, it is (i) Multiple of 5 (ii) Greater Than 70 (iii) Multiple of 7​

Answer 1

Answer:

(iii) multiple of 7 is the right answer mark me brainest plz

Answer 2

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)=

Number of possible out comes

Number of favourable out comes

P(E)=14/99

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