Step-by-step explanation:
Given that a restaurant chef prepares a tossed salad containing, on average, 5 vegetables per day.
We can assume the number of vegetables used by the chef per day is
Poisson with parameter = mean = 5
We are to find the probability that the salad contains more than 7 vegetables on i) a given day and on ii)3 of the next 6 days?
a) P(no of vegetables >7) = 1-F(7) = 1-0.8666
=0.1334
b) For 6 days we can say each day is independent of the other
Prb( veg >3) for 6 days
= P(veg>3)^6
Answer:
6

4×3=12
12/2=6
6 apples in 2 bowls
I’m pretty sure it’s c , sorry if it’s wrong tho
Answer:
P(X ≤ 5) = 0.84134
Step-by-step explanation:
This is a normal distribution problem with
μ = mean = 4 years
σ = standard deviation = 1 year
To find the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5)
- Use an empty cell.
- Right click and go to “Insert Formula”.
- In the searchbox, type “Normdist” and click “Go.”
- Pick “NORMDIST” from the list and then click “OK” to open the Function Arguments window.
- Enter the data into the box. Type “5” in the X box, “4” in the Mean box, “1” in the Standard Deviation box and “true” in the cumulative box..
- Click “OK.”. This returns 0.84134474 in the cell you clicked in Step 1, which is the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5).
P(X ≤ 5) = 0.84134
