Answer:
Experimental
Step-by-step explanation:
It is not a theory he actually tossed the penny
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

5. a), </h3><h3>
6. c), </h3><h3>
7. ⁵/₃ or 5÷3 or 1 ²/₃</h3>
Step-by-step explanation:
1. 0 divided by any number is always 0
2. 7×(5-5) = 7×0 = 0
3. Integers between -5 and 5 are:
-4, -3, -2, -1, 0, 1, 2, 3 and 4
4. - ( |5 - 11| ) = - ( |-6| ) = - ( 6 ) = -6
5. Numerical coefficient is the number with its sign. No letters.
6. x increased by y means: y more than x. And x+y = y+x
7. one third of 5 means 
so it is:
