Syllogism (Clear Your Basics)
10 Questions 10 Marks 10 Mins
GIVEN:
The number should be multiple of 4 and 5
CONCEPT:
For a number to be a multiple of two numbers it should be the multiple of their L.C.M
FORMULA USED:
P = Favorable outcomes/Total outcomes
CALCULATION:
Total 2 digit numbers = 90 (from 10 to 99)
The number should be divisible by 20 (L.C.M of 4 and 5)
2 digit numbers divisible by 20 are, 20, 40, 60, 80
Required probability = 4/90 = 2/45
∴ The probability is 2/45.

number of two-digit numbers:
10, 11, ... , 99, ----> 90 of them (1 - 9 are missing)
smaller than 20:
10,11, ... , 19 ----> 10 of them
prob( < 20) = 10/90 = 1/9
use the same type of analysis for the two other parts, let me know what you get.
What is the probability that a two digit number chosen random?
There are 90 two digit numbers(99–9). Out of this there are 6 numbers divisible by 15(15, 30, 45, 60, 75, 90), which are also divisible by 5. Therefore, the favorable cases are 30–6=24. Hence, the required probability is 24/90 = 4/15.What is the probability that a two digit number selected random will be a multiple of 3 and not a multiple of 5 '?
