A द्वारा निशाना लगाने की प्रायिकता, P(A) = 2/3
B द्वारा निशाना लगाने की प्रायिकता, P(B) = 3/4
प्रयुक्त सूत्र:
A द्वारा निशाना नहीं लगाने की प्रायिकता, P(A') = 1 - P(A)
B द्वारा निशाना नहीं लगाने की प्रायिकता, P(B') = 1 - P(B)
ठीक एक के निशाना लगाने की प्रायिकता = P(A)xP(B') + P(A')xP(B)
गणना:
P(A') = 1 - 2/3 = 1/3
P(B') = 1 - 3/4 = 1/4
ठीक एक के निशाना लगाने की प्रायिकता = (2/3)x(1/4) + (1/3)x(3/4)
⇒ 2/12 + 3/12 = 5/12
इसलिए, उनमें से ठीक एक के निशाना लगाने की प्रायिकता 5/12 है।
