P(A) = 0.60
P(B/A) = 0.10
अवधारणा:
P(A | B) ⋅ P(B) = P(B | A) ⋅ P(A)
गणना:
माना A घटना है : कर्मचारी स्नातक हैं।
माना B घटना है : कर्मचारी विक्रय में हैं।
⇒ P(B) = P(A).P(B/A) + P(A’). P(B/A)’
⇒ 0.60 × 0.10 + 0.40 × 0.80
∴ यादृच्छिक रूप से चयनित कर्मचारी के विक्रय में होने की प्रायिकता 0.38 है।
Important Points
प्रायिकता हमेशा 0 से 1 के बीच होती है।
