so, your answer is 20/100=1/5
You can ask for explanation if you want to.
Step-by-step explanation:
Probability P(A)= 22/100
Explanation:
Given:
Number being picked from 1 to 100 is divisible by 3 not by 9
To find:
The probability of a number
Formula:
Probability P(A) = Number of outcomes/ Total number of outcomes
P(A)= n(A)/n(S)
Total number of outcomes = 100
n(S)=100
Solution:
The number which is divisible by 3
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99
The number which is divisible by 3 is 33
From the number we have to find the number which is not divisible by 9
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99
The number which are divisible by 3 and not divisible by 9
3, 6, 12, 15, 21, 24, 30, 33,39, 42, 48, 51, 57, 60, 66, 69, 75, 78, 84, 87, 93, 96
The number which are divisible by 3 and not divisible by 9 is 22
n(A)=22
Probability P(A) = Number of outcomes/ Total number of outcomes
P(A)= 22/100
