What is the sum of the probabilities of all the outcomes in a sample space?
1.
How do you construct a probability distribution?
First decide whether the event space is discrete or continuous.For a discrete event space, for each outcome in the space assign a probability: a number in the interval [0, 1] such that the sum of probabilities for all outcomes is 1. The mapping from the event space to the probabilities is the probability distribution function.The procedure for a continuous event space is analogous: the sum is replaced by the integral.
What is true about the sum of the angles of any triangle?
No matter what, all three angles of the triangle will ALWAYS add up to 180 degrees.
What is the exterior angle sum of regular heptagon?
The exterior angle sum is 360 degrees. It doesn't matter whether the polygon is regular or not, and it doesn't even matter how many sides it has.
What is the sum of the exterior angles in a convex figure with three sides?
The sum of the exterior angles of any polygon - no matter how many sides, no matter whether it is convex or concave - is 360 degrees.
