Answer:
Step-by-step explanation:
From the question we are told that:
Sample size
N0 of Large
N0 of Small
N0 large Green
N0 of small White
Therefore
Number of green marbles
Number of green marbles
Generally the Number of both small and green Marble is
Generally the probability that it is small or green P(S&G) is mathematically given by
Answer:
108°
Step-by-step explanation:
Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).
The sum of all interior angles of pentagon can be calculated using following formula
All interior angles in regular pentagon are of equal measure, so
Thus, the measure of each angle formed by the lights on the perimeter is 108°.
