Question

What is the probability that a number selected at random from the numbers 3, 4, 5, ....9 is a multiple of 4? 

Answer 1

 numbers are 3, 4, 5, 6…9

TO FIND: Probability of Getting multiple of 4

Total number is 9−3+1=7

Numbers which are multiple of 4 between 3 and 9 are 4 and 8 Total number which are multiple of 4 between 3 to 9 is 4 and 8 is 2

`"We know that PROBABILITY" = "Number of favourable event" /"Total number of event"` 

Hence probability of getting a number which is a multiple of 4 is `2/7`

Hence probability of getting a number which is a multiple of 4 is equal to `2/7`
