(c)
The sum of n natural numbers is \(\dfrac{n(n-1)}{2}\), so we have \(\dfrac{99(100)}{2}=4950\)
(b)
He didn't write down a 0. Using \(\text{Probability}=\dfrac{\text{number of successful outcomes}}{\text{total possible outcomes}}\), the probability is 0.
(a)
Let's look at a simplified version: 1, 2, 3, 4. How many numbers are in that?
