At a certain pizza parlor, 43% of the customers order a pizza containing onions, 33% of the customers order a pizza containing sausage, and 67% order a pizza containing onions or sausage (or both). find the probability that a customer chosen at random will order a pizza containing both onions and sausage.



9%

Step-by-step explanation:

The percentage that a customer request for a pizza that contains onion = 43%

The percentage that a customer request for a pizza that contains sausage = 33%

The percentage that a customer request for a pizza that contains onion and/or sausage = 67%

We can represent this using probability notations

P(Onions) = 43% = 0.43

P(Sausage) = 33% = 0.33

P(Onions and/or Sausage) = 67% = 0.67

P(Onions and/or Sausage) can be translated to customers that request for pizza containing "Onions only" , "Sausage only", "Onions and Sausage"

Mathematical, we represent the above statement:

P(Onions) + P(Sausages) - P(Onions and Sausage)

So, we have

P(Onions and/or Sausage) = P(Onions) + P(Sausages) - P(Onions and Sausage)

0.67 = 0.43 + 0.33 - P(Onions and Sausage)

0.67= 0.76 - P(Onions and Sausage)

P(Onions and Sausage) = 0.76 - 0.67

P(Onions and Sausage) = 0.9

So, the probability of a customer making an order of pizza that contains onions and sausage is 0.9 or 9%

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
