Question

A bank ATM has notes of denomination 100, 500 and 1000 in equal numbers. what is the probability of getting a note of Rs. 1000 ?

Answer 1

let there be x no. of Rs.100 ,Rs 500 and Rs.1000 notes each..so total no. of notes =x+x+x= 3x...so probability of getting a note of Rs.1000 will be= x/3x=1/3=1:3

Answer 2

"The “Probability” of getting Rs.1000 note is  

Given data:

The bank ATM has denomination of 100, 500, and 1000 rupees notes.

To find:

The “probability” of getting Rs.1000 note = ?

Solution:

Let X be the number of 100, 500 and 1000 rupees note.

So the total number of notes is X + X + X = 3X

Then the probability of getting Rs.1000 note is $\frac{X}{3 X}$

Thus, we get, 1 : 3"
