The number of three-digit numbers that can be formed with 0, 1, 2, 3, 4 is, when repetition is not allowed.

The number of three-digit numbers that can be formed with 0, 1, 2, 3, 4 is, when repetition is not allowed. Correct Answer 48

Calculation:

Number of digits = (0, 1, 2, 3, 4) = 5

Given: Repetition is not allowed

The first digit should not be 0. So, there are 4 possibilities (1, 2, 3, 4)

Next for the second digit can have any of the one other than the one used in the first place. So, again 4 possibilities.

Similarly, the third digit will have 3 possibilities (removing the two used digits) 
So total no of 3-digit no. = 4 × 4 × 3 = 48

The digits 1 to 9 are arranged in three rows in such a way that each row contains three digits, and the number formed in the second row is twice the number formed in the first row; and the number formed in the third row is thrice the number formed in the first row. Repetition of digits is not allowed. If only three of the four digits 2, 3, 7 and 9 are allowed to use in the first row, how many such combinations are possible to be arranged in the three rows?
There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.

Consider the following policies for preventing deadlock in a system with mutually exclusive resources. I. Processes should acquire all their resources at the beginning of execution. If any resource is not available, all resources acquired so far are released II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger than its currently held resources Which of the above policies can be used for preventing deadlock?
