Question

What is the probability of getting a multiple of 8 between 1 and 100?

Answer 1

Answer:

6/49

Step-by-step explanation:

a = 8

aₙ = 96

d = 8

aₙ = a + (n-1)d

aₙ = a + dn - d

96 = 8 + 8n - 8

8n = 96

n = 12

total number of numbers divisible by 8 between 1 to 100 is 12

total number of numbers between 1 to 100 is 98

so p(getting a multiple of 8 between 1 and 100) = number of favourable outcomes/ number of total outcomes = 12/98 = 6/49.
