`therefore` पाँसे पर कुल संख्याओं का होना 6 है |
अर्थात `S = {1,2,3,4,5,6}`
ज्ञात है: `A = {2,4,6}`
तथा `B = {2,4,6}`
अब `A nn B = {2,4,6}`
तब `P(A) = (3)/(6)=(1)/(2),P(B) = (3)/(6)=(1)/(2)`
तथा `P(A nn B ) = (3)/(6) = (1)/(2)`
स्पष्ट है : `P(A nn B) ne P(A).P(B)`
अतः A तथा B स्वतंत्र घटनाएँ नहीं है |
