4 - Machines are linked to a drain, each has an individual probability of discharge of 0.24 based on the individual discharge rate in seconds over interval of discharge therfore for a single machine (p) = t/T = 0.24

Need to know how to calculate the combined discharge for 4-machines each having same (p) = 0,24 to arrive at the maximum flow rate

Something's value changes randomly over time. Assume normal (Gaussian) distribution. I know that it spends X% of its time greater than BIGNUMBER and (equally) X% of its time smaller than SMALLNUMBER. It's symetric, not skewed or anything weird like that, and so the mean is the mean of BIGNUMBER and SMALLNUMBER.

What's the standard deviation??

Thanks!!!
