4. Susannah is drawing a card from a standard 52-card deck. A standard deck of cards contains four suits -- diamond, club, spade & heart. Each suit has 13 cards. Face cards (12)

are Jack, Queen, and King cards.

a. What is the probability that the card she draws is a diamond?

b. What is the probability that the card she draws is a face card?

c. What is the probability that the card she draws is a face card and a diamond?

d. What is the probability that the card she draws is a face card or a diamond?

a

step-by-step explanation:

its wrong

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
