How many times does the digit 2 occur between 1 and 100?
Detailed Solution Digit 2 appears 20 times in first 100 natural numbers.
How many times does the digit 6 come between 1 and 100?
Answer and Explanation: If you count from 1 to 100, you will encounter 20 sixes. There is one six in every set of 10 (6, 16, 26, 36, 46, 56, 66, 76, 86, and 96).
How many times will the digit 8 be written when listing the integers from 1 to 1000?
Means Upto 1000, we will encounter 200 8s. 8s. Hence total 300 ‘8s’.

What is the third problem with the multiplication principle?
The third problem illustrates a dependency that makes the multiplication principle not applicable. For example, if the first two digits are 01, the last two digits would be 03, 04, 05, 06, …, 99 for a total of 97 possibilities. If the first two digits are 02, then there are 94 possibilities for the last two digits (06, 07, …, 99).
What is two step multiplication principle?
The Multiplication Principle Two step multiplication principle: Assume that a task can be broken up into two consecutive steps. If step 1 can be performed in m ways and for each of these, step 2 can be performed in n ways, then the task itself can be performed in m n ways. Example 1 Suppose you have 3 hats, hats A, B and C,
How many possible subsets does the multiplication principle have?
Thinking of the problem in this way, the Multiplication Principle then readily tells us that there are: or 2 10 = 1024 possible subsets. I personally would not have wanted to solve this problem by having to enumerate and count each of the possible subsets.
