The correct answer is <span>{-5/2, 10/3}.</span>
Let event A be the coin landing on heads and let event B be rolling a 5 on a six-sided die.
Events A and B are independent if, and only if:

It is given in the question that the above condition for independence is met.
Also A and B are independent if:
P(A|B) = P(A)
P(A) = 1/2
Therefore the probability of flipping a coin and it landing on heads, given that you rolled a 5 on a six-sided die is 1/2. The two events are independent.
Not A because regular means all sides are equal.
B has to be the answer because the others are not.
Not C because a right triangle is not regular, i.e. and equilateral triangle.
Not D because a rectangle has different side lengths.

Answer:
2 1/2 cups
Step-by-step explanation:
A proportion says the ratio of one thing to another is the same for different amounts. Here, we want cups, so we can use the proportion ...
cups/people = 2/12 = x/15 . . . . . where x is the number we want to find
Multiplying by 15 gives ...
x = 15(2/12) = 5/2 = 2 1/2
You will need 2 1/2 cups of zucchini to feed 15 people with the same recipe.
