Answer:
Step-by-step explanation:
hello :
f(t) = 1/t - 1
calculate : t
f(t)+1 = 1/t so : t = 1/(f(t)+1)
f^ -1 (t)= 1/(t+1)
Find the probability of getting a sum of 35 while rolling 10 number cubes.
we know that
posiible outcomes=6x6x6x6x6x6x6x6x6x6=6^10=60,466,176
To find out the number 35
35=8(4)+2+1
35=6(5)+2+ 1+1+1
35=5(5)+5(2)
35=4(5)+4(3)+2+1
35=3(5)+4(4)+2+1+1
35=5(6)+5(1)
35=4(6)+5(2)+1
35=3(6)+2(5)+2(2)+3(1)
35=2(6)+5+
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
