1) एका पिशवीत 5 पांडरे चेंडू आणि काही निळे चेंडू आहेत, जर निळा चेंडू काहण्याची संभाव्यता पांढरा
चेंडू काढण्याच्या संभाव्यतेपेक्षा दुप्पट असेल, तर पिशवीतील निळ्या चेंडूची संभाव्यता काढा.
Answers
Given :- There are 5 white balls and some blue balls in a bag, if the probability of hitting a blue ball is double the probability of drawing a white ball, then find the probability of a blue ball in the bag ?
Solution :-
Let us assume that total blue balls in the bag are x .
so,
→ Total balls in the bag = (5 + x) balls .
A/q,
→ Probability of hitting a blue ball = 2 * Probability of hitting a white ball .
→ x/(5 + x) = 2{5/(5 + x)}
→ x/(5 + x) = 10/(5 + x)
→ x = 10 .
then,
→ Probability of a blue ball in the bag = 10/(10+5) = 10/15 = (2/3) (Ans.)

There are 5 white balls and some blue balls in one bag.
the probability of removing the blue ball is twice the probability of removing the white ball
To Find : Probability of removing blue ball from the the bag
पिशवीतील निळ्या चेंडूची संभ्यवत्या काढा
Solution:
P (W) = x
P(B ) = 2 P(W)
=> P(B ) = 2x
P(B) + P(W) = 1 as only blue and white balls in the bag
=> 2x +x = 1
=> 3x = 1
=> x = 1/3
=> 2x = 2/3
=> P(B) = 2/3
