दिया गया है

P(3) = P(4)

अवधारणा

प्वासों वितरण में = यह एक असतत विभाजन भी है। प्वासों वितरण सामान्य वितरण की सीमा को पूरा करता है

प्वासों वितरण दिया जाता है f(x) = (e × λx)/x!

जहाँ x = 0, 1, 2, 3---- और λ = माध्य

गणना

यहाँ x = 3 और 4

(e × λ3)/3! = (e × λ4)/4!

⇒ λ  = 4!/3!

⇒ λ = 4

प्वासों वितरण में x का माध्य 4 है।
