Download Solution PDFदिल्याप्रमाणे
P(A) = 0.60
P(B/A) = 0.10
संकल्पना:
P(A | B) ⋅ P(B) = P(B | A) ⋅ P(A)
गणना:
समजा A ही घटना आहे: कर्मचारी पदवीधर आहेत
समजा B ही घटना आहे: कर्मचारी विक्री विभागात आहेत
⇒ P(B) = P(A).P(B/A) + P(A'). P(B/A)'
⇒ 0.60 x 0.10 + 0.40 x 0.80
∴ यादृच्छिकपणे निवडलेला कर्मचारी विक्रीत असण्याची संभाव्यता 0.38 आहे
Important Points
संभाव्यता नेहमी 0 ते 1 दरम्यान असते
