Pam wants to put a banner across her garage door, as shown below, to congratulate her son for his college graduation. The garage door is 12 feet high and 16 feet wide. How long should the banner be to fit the garage door?

Question is not clear enough

I'll assume the question is this:

A fair coin has 2 sides (heads and tails) that are equally likely to show when the coin is flipped. What is P(tails)?

P(tails) = 0.5

Step-by-step explanation:

Given:

Number of sides = 2

Number of head = 1

Number of tails = 1

Let P(Tail) = Probability of obtaining a tail when the coin is flipped.

P(Tails) is calculated as follows;

P(Tails) = Number of Tails/Total Number of Sides

Substitute in the values of Number of Tails and Total Number of Sides

P(Tails) = 1/2

P(Tails) = ½

P(Tails) = 0.5

Hence, the probability of obtaining a tail provided that the two sides of the coin are equally likely to show when the coin is flipped is 0.5
