Answer:
The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
Answer: Yes, they are equal
lets see how,
solve the given equation,
–3(0.15 – 0.2 + 0.25p)
Step 1: Inside the bracket solve the similar variables i.e. (0.15 - 0.2)
So it will become,
= -3 ( -0.05 + 0.25p )
Step 2: Multiply each term in the bracket by -3
So it will be,
((-3*-0.05 ) + (-3 * 0.25p))
= 0.15 - 0.75p
Hence 0.15 – 0.75p is equal to –3(0.15 – 0.2 + 0.25p )
