A bag contains 12 blue balls and x red balls. If one ball is drawn at random (i) what is the probaility that it will be a red ball ? (ii) If 8 more red balls are put in the bag, and if the probability of drawing a red ball will be twice that of the probaility in (i), then find x.

A bag contains 18 balls.out of which x are red. (i) If one ball is drawn at random from the bag, the what is the probability that it is a red ball ? (ii) If 2 more red balls are put in the bag, then probability of drawing a red ball will be 9/8 times that of red ball coming in part (i), find value of x.

A bag contains 4 black balls and 6 red balls. One ball is drawn at random. The probability that it is red is

A bag contains 3 white and 2 red balls. One ball is drawn at random. What is the probability that the ball drawn is red?

A bag contains 30 white and 10 red balls. One ball is drawn at random. What is the probability that the ball drawn is red?

A bag contains 18 balls out of which x balls are red. (i) If one ball is drawn at random from the bag what is the probability that it is not red? (ii) If two more red balls are put in the bag, the probability of drawing a red ball will be (9)/(8) times the probability of drawing a red ball in the first case. Find the value of x.

A bag contains 18 balls out of which x balls are red. (i) If one ball is drawn at random from the bag what is the probability that it is not red? (ii) If two more red balls are put in the bag, the probability of drawing a red ball will be (9)/(8) times the probability of drawing a red ball in the first case. Find the value of x.

A bag contains 18 balls out of which x balls are red. (i) If one balls is drawn at random from the bag, what is the probability that it is not red? (ii) If two more red balls are put in the bag, the probability of drawing a red ball will be 9/8 times the probabability of drawing a red ball in the first case. Find the value of x.
