Answer:
4845 combinations
Step-by-step explanation:
Whenever there is a selection of some elements from a certain group, there are several ways to do so. There are different combinations from the group which can be selected. The concept of combination means that there are certain number of elements to be selected from the group and there is no importance given to the order of the selection. The total number of students are 20, and 4 out of them have to be selected. It can be clearly seen that the order of selection does not matter, therefore the formula to be used is:
Combinations = 20C4 = (20*19*18*17)/(4*3*2*1) = 4845.
So the correct answer is 4845 combinations!!!

Answer:
- <em>An integer is not negative if and only if it is not less than zero.</em>
Step-by-step explanation:
Observing each statement individually:
- <em>An integer is negative if and only if it is not less than zero</em>
A number that is NOT less than 0 is greater than zero. Negative numbers are less than 0, so this is clearly incorrect.
- <em>An integer is not negative if and only if it is less than zero.</em>
A number that is NOT negative is positive. Positive integers are integers greater than zero, so this is also incorrect.
- <em>An integer is not negative if and only if it is not less than zero.</em>
A number that is NOT negative is positive. A number that is NOT less than zero is greater than zero, or positive. This statement is correct.
- <em>An integer is less than zero if and only if it is not negative.</em>
A number that is less than zero is negative, and this statement claims that a number less is only less than zero if it is NOT negative. This is incorrect.
