Q

P(X < x) = ? (to calculate the area under the curve to the left, in the graph of exponential distribution)

A

P(X < x) = 1 - e^(-λx) (για την αριστερή περιοχή, κάτω από την καμπύλη - αριστερά του x)

Q

P(X > x) = ? (to calculate the area under the curve to the right, in the graph of exponential distribution)

A

P(X > x) = e^(-λx) (για την δεξιά περιοχή, κάτω από την καμπύλη - δεξιά του x)
