Answer:
x = 3.2
Step-by-step explanation:
4(x – 2) = 6(4 – x)
4x - 8 = 24 - 6x
10x - 8 = 24
10x = 32
x = 3.2
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
