Actually Welcome to the Concept of the Probability.
Basically we have to know that, when there is a specific event for which a probability has to be done, there are always two possibilities that is,
Event favourable and Not Favourable.
the Sum of both always end up as 1.
thus sum of the probability distribution is 1.
Correct. 2 x 2 = 4, 4 + 2 = 6 cubes.
Answer:
-12
Step-by-step explanation:
5 + -2 = 3
-4 x 3 = -12
A nonagon has 9 sides
The formula for the sum of all the interior angles of a polygon is 180(n-2) where n is the # of sides. Then the answer is:
180*(9-2)
180 * 7
1260 is the answer
