यदि `P(bar(A))=0.7, P(B)=0.7` और `P(B/A)=0.5` तब `P(A/B)` और `P(A uu B)` ज्ञात कीजिए।

Explanation

हम जानते हैं, की ,brgt `P(bar(A))=1-P(A)`
`implies P(A)=1-P (bar(A))`
`implies P(A)=1-0.7=0.3`
अब, `P(B/A)=(P(Ann B))/(P(A))`
`implies 0.5=(P(A nn B))/0.3`
`implies P(A nn B)=0.3xx0.5=0.15`
`:. P(A/B)=(P(A nn B))/(P(B))=0.15/0.7=3/14`
और `P(A uu B)=P(A)+P(B)-P(A nn B)`
`implies P(A uu B)=0.3+0.7-0.15`
`implies P(A uu B)=0.85`.
