P(3) = P(4)
অনুসৃত ধারণা
পয়সন বিভাজন = এটি একটি বিচ্ছিন্ন বিভাজনও। পয়সন বিভাজন স্বাভাবিক বিভাজনের সীমাবদ্ধতা পূরণ করে
পয়সন বিভাজন f(x) = (e-λ × λx)/x! দ্বারা প্রদত্ত!
যেখানে x = 0, 1, 2, 3 ---- এবং λ = গড়
গণনা
এখানে x = 3 এবং 4
⇒ (e-λ × λ3)/3! = (e-λ × λ4)/4!
⇒ λ = 4!/3!
⇒ λ = 4
∴ পয়সন বিভাজনে x এর গড় হল 4
