Answer 1

Answer:

Step-by-step explanation:

(i) यहाँ पे,

P(A) = 1/3' , P(B) = 1/5', P(A ⋂ B) = 1/15

हम जानते हे की P(A U B) = P(A) + P(B) -  P(A ⋂ B)  

=>  P(A U B)  = 1/3 + 1/5 - 1/15

=>  P(A U B) = 5 + 3 - 1 / 15

=>  P(A U B) = 7/15

(ii) यहाँ पे,

P(A) = 0.35 , P(A ⋂ B) = 0.25, P(A U B) = 0.6

हम जानते हे की P(A U B) = P(A) + P(B) -  P(A ⋂ B)  

=>  0.6  = 0.35 + P(B) - 0.25

=>  P(B) = 0.6 - 0.35 + 0.25

=>  P( B) = 0.5

(iii) यहाँ पे,

P(A) = 0.5 , P(B) = 0.35, P(A U B) = 0.7

हम जानते हे की P(A U B) = P(A) + P(B) -  P(A ⋂ B)  

=> 0.7 = 0.5 + 0.35 - P(A ⋂ B)  

=>  P(A ⋂ B) = 0.5 + 0.35 - 0.7

=> P(A ⋂ B)  = 0.15
