Answer:
The probability is 0.5086
Step-by-step explanation:
The probability P that at least one of these three modules will fail to work properly is calculated as:
P = 1 - P'
Where P' is the probability that all the modules works properly. So, P' os calculated as:
P' = 0.9 * 0.84 * 0.65
P' = 0.4914
Because 0.9 is the probability that module 1 works properly, 0.84 is the probability that module 2 works properly and 0.65 is the probability that module 3 works properly.
Finally, the probability P that at least one of these three modules will fail to work properly is:
P = 1 - 0.4914
P = 0.5086
Answer:
yes it is
Step-by-step explanation:
The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
