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:
k-n+1
Step-by-step explanation:
How many numbers are written from n to k
Lets look at a smaller example with real number
Lets go from 3 to 8
3 4 5 6 7 8
There are 6 numbers
We take 8 -3 = 5, but we include the number 3 so we add it back in +1
5+1 =6
Lets look at a larger example
2 to 11
2,3,4,5,6,7,8,9,10,11
There are 10 numbers
11-2 =9 but we have to add back in the first number
9+1 =10
Now we are going from n to k
k-n = k-n, but we have to add back in the first number
k-n+1
Answer is 63
180-(70+47)=63
Because in triangle sum of all angles is 180 degree.
Figure RST is congruent to figure R'S'T
First, we need to make a function out of the table. This function will be in slope-intercept form. The function is y = 30x so in 11 minutes Machine J will make 330 candies. In 11 minutes Machine K will make 286. subtract 286 from 330 to get 44. Machine J will make 44 more candies than machine K in 11 minutes.
