Answer:
the probability of drawing three consecutive red marbles is based on how many red marbles you have and many marble there is in total.
Look up "sum of interior angles of a polygon" on Google. There you will find a formula for predicting the number of interior angles that a given polygone will have. This formula is <span> (n - 2) × 180°, where n represents the number of sides of the polygon in question. Count these sides. Substitute your value for n into this formula. The interior angles of your polygon add up to the result of evaluating this formula. Call this "sum." Then:
"sum" = (the one unknown interior angle) + (the sum of the given (known)) interior angles).</span>

Answer: 5 * (1/6)</h3>
5 is the whole number, 1/6 is the unit fraction. A unit fraction is a fraction with 1 as the numerator.
We can think of 5 as 5/1
When we multiply 5/1 with 1/6, we get
(5/1)*(1/6) = (5*1)/(1*6) = 5/6
Use this rule to multiply fractions
(a/b)*(c/d) = (a*c)/(b*d)
You multiply the numerators together, and the denominators together.
