When a fair die is thrown, the probability of getting each of the digit 1,2,3,4,5 and 6 is 16 . Of these, digits divisible by 3 are 3 and 6. Hence when you roll a fair die once, probability of getting a number divisible by 3 is 26 or 13 .
What is the probability that a 3 digit number is divisible by 3?
We have 900 three digit numbers from 100 to 999. 300 of them 102,105,…,999 are divisible by 3. So, the answer to the first question is 300/900 = 1/3.
What are all the numbers divisible by 3?
A number is divisible by 3 if the sum of its digits is also divisible by 3. For example, 5502 is divisible by 3 because 5 + 5 + 0 + 2 = 12. 12 is divisible by 3 and so, 5502 is divisible by 3.
How many possible outcomes are there when you roll a dice 3 times?
216 outcomes
Possible Outcomes and Sums Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice.
What is the probability of getting a number is divisible by 3 or 4?
Hence the required probability is 4/6 or ⅔ . 3,6,9,12 are the sums divisible by 3. 4 and 9 are the squares.
What is the probability that it is a number divisible by 3 or divisible by 4?
6/12 possibilities, so the answer is 1/2 probability that you’ll land on a number divisible by 3 or 4.
What are the whole numbers between 1 and 100 divisible by 3 6 and 9?
Thus there are 5 whole numbers between 1 and 100 divisible by 3, 6 and 9: 18, 18×2=36, 18×3=54, 18×4=72 and 18×5=90.
How to count how many numbers are divisible by 3?
Use the empty list as an edge case where you return 0, so you can add 1 every time one element of the list is dividable by 3 without rest. If you can divide the element by 3 without rest you add 1 and call the function again with the list else you just add 0, e.g.
How to test for the divisibility of a number?
An online calculator to test for divisibilty by 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13. 1 – Enter a whole number n and press “enter”. If “yes” is displayed beside a number, it means n is divisible by that number. If “no” is displayed, it means n is not divisible by that number. Divisibilty Questions With Solutions .
What are the possible outcomes of Game 2?
