Hi i am working on a Binomial Distribution
If i know the Mean of A is 7.6
and
I know the Variance of A is 5.48
How do you write an expression that A >= 28?
So as the question is put chances of having a work accident is on a weekday is .2 and weekend is .3
A is random variable representing no. of accidents in february
mean of A is 7.6
variance of A is 5.48
for P(<=28)= 1-P(>=27) = 1-Bin(27,?,?.....
Am i on the right path here?
