How many ways can 5 numbers be arranged?
120 ways
Note that your choice of 5 objects can take any order whatsoever, because your choice each time can be any of the remaining objects. So we say that there are 5 factorial = 5! = 5x4x3x2x1 = 120 ways to arrange five objects. In general we say that there are n!
What is the probability that the sum is 7?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
How are the 7 digits of a number obtained?
The place value of the seven digits that make up the 7-digit number are obtained by progressively multiplying the respective figure by 1, 10, 100, 1,000,10,000, 1,00,000, and 10,00,000, starting from the rightmost digit and moving to the left, as per Indian number system.
How many pairs of numbers add to 10?
However to memorise number bonds to 10, we can see that there are only five pairs of numbers to remember. The pairs of numbers that add to make 10 are: Remembering 5 pairs of numbers is easier than remembering 10 separate addition facts. For example: 1 + 9 contains the same pair of numbers as the number bond of 9 + 1.
How are 7 digit numbers written in expanded form?
A 7-digit number can be written in the expanded form as per the place value of each of the digit in that number. For example, 99,88,913 = 90,00,000 + 9,00,000 + 80,000 + 8,000 + 900 + 10 + 3.
