FAQs on Test Papers. (a)Compute (i) 20! 18! (ii) 10!

What is the sum of all the 4 digit numbers formed by 2 3 4 5 without repetition?

The sum of all the 4-digit numbers formed using the digits 2, 3, 4, and 5 (without repetition) is 93, 324.

How many numbers can be formed from sum of all the digits 2 3 4 5 if number do not have repeated digits?

To find the sum of all the four digit numbers formed using the digits 2,3,4 and 5 without repetition: We can form a total of 4! or 24 numbers.

How many numbers can be formed using the digits 1 2 3 without repetition?

Total Number of Numbers which can be formed by numbers 1,2,3,4,5 (without repeating digitsi) = 5*4*3*2*! = 5! = 120.

What is the sum of all 4 digit numbers that can be formed using the digits 1 2 3 4 without repetition?

Sum of all digits in each place = 64 ( 1+2+3+4 ) = 640.

What is the sum of all the 4 digit numbers that can be formed using all of the digits 2 3 5 and 7 with repetition?

The sum of all 4-digit even numbers formed by the digits 0,1,2,3,5,7 (without repetition) is. 239760.

How sum of all numbers is?

+n = n(n+1)/2. So limit n tends to infinity Sn is infinity . so sum of all natural numbers is infinity. As sequence of partial sum divergent so series is also divergent and diverges to infinity. many summation methods are used in mathematics to assign numerical values even to a divergent series.

What is the sum of all 96 numbers at random?

If you pick one at random, the expected value of the first digit is 1 + 2 + 3 + 4 4 = 5 2, and the expected value of each other digit must be 15 8, because the sum of all five digits is 0 + 1 + 2 + 3 + 4 = 5 2 + 4 ⋅ 15 8. By linearity of expectation, the sum of all 96 numbers is 96 ( 5 2 ⋅ 1000 + 15 8 ⋅ 111) = 259980.

How many 4 digit numbers can be formed using 1 2 3 4?

The total no. of 4 digit numbers can be formed using 1,2,3,4 without repetition is 4! = 24. So in each place of the 4 digit number 24 digits are possible which are 1,2,3,4 so from symmetry we can say in each place there will be six 1, six 2, six 3, six 4.

What is the total number of a 3 digit number?

The first digit of a 3-digit number can be selected from a group of 5 numbers. The second digit, allowing no repeats, can be selected from the remaining 4 numbers. Similarly, the last and 3rd digit can be selected from the remaining 3 numbers. The total number is thus 5 x 4 x 3 = 60.

How many possible numbers are there in 4 ⋅4⋅3 ⋄ 2?

No repetitions allowed. There are 4 ⋅ 4 ⋅ 3 ⋅ 2 = 96 possible numbers (not 5 ⋅ 4 ⋅ 3 ⋅ 2, since the first digit must by nonzero).
