Question

a number is selected from 1 to 100 find the probability that the number is divisible by 446​

Answer 1

Answer:

4/25

Step-by-step explanation:

Given sample space S = {1,2,3,−−−100}

numbers divisible by 8 below 100P1​ = {8,16,24,−−−96}

number divisible 12 below 100,P2 ​= {12,24,−−−96}

numbers divisible by 8 and 12 below 100,(P1​∩P2​) = {24,48,72,96}

n(P1​) = 12

n(P2​) = 8

n(P1​∩P2​) = 4

∴ Probability of Selecting a number divisible by 8 or 12

is = n(P1​) + n(P2​) − n(P1​∩P2​)​/n(s)

=12 + 7 − 4​/100 = 16/100​

Probability = 4/25

Answer 2

Answer:

A number is selected at random from first 100 whole numbers. Find the probability that the number is divisible by 8 or 12 .
