The probability that a customer orders coffee or pie is 21/26 or 0.8
<u>Step-by-step explanation:</u>
It is given that,
26 customers are eating dinner at a local diner.
The total number of customers = 26
Of the 26 customers,
- 20 order coffee
- 8 order pie and
- 7 order coffee and pie.
<u>To find the probability that a customer orders coffee or pie :</u>
The formula used is P(A or B) = P(A) + P(B) - P(A∪B)
Here,
- The event A is ordering coffee.
- The event B is ordering pies.
P(coffee) = No.of customers order coffee / Total customers
⇒ 20 / 26
P (pie) = No.of customers order pie / Total customers
⇒ 8 / 26
P (coffee and pie) = No.of customers order both / Total customers
⇒ 7 / 26
P (coffee or pie) = P(coffee) + P(pie) - P (coffee and pie)
⇒ 20/26 + 8/26 - 7/26
⇒ 21/26
⇒ 0.8
∴ The probability that a customer orders coffee or pie is 21/26 or 0.8
Answer:
the answer would have to be B
Step-by-step explanation:
Answer:
63 yd²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 7 and h = 9, thus
A = 7 × 9 = 63 yd²
They're both functions because each input has exactly one output
So since x= sand bags replace x with 0 so 7y=105 is left divide by 7 and you get y=15 so 15 bags
