At a pizza shop, 75% of the customers order pizza, 20% of the customers order salad, and 15% of the customers order a pizza and a salad. if a costumer isn’t chosen at random, what is the probability that he or she orders either a pizza or salad?

The probability that he or she orders either a pizza or salad is 80%.

Step-by-step explanation:

Given : At a pizza shop, 75% of the customers order pizza, 20% of the customers order salad, and 15% of the customers order a pizza and a salad. If a costumer isn’t chosen at random.

To find : What is the probability that he or she orders either a pizza or salad?

Solution :      

Let A be the event that customer order Pizza

Let B be the event that customer order Salad

75% of the customers order pizza,

P(A)=75%=0.75

20% of the customers order salad,

P(B)=20%=0.20

15% of the customers order a pizza and a salad,

Now, The probability that he or she orders either a pizza or salad

Therefore, The probability that he or she orders either a pizza or salad is 80%.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
