A bag contains some black beads and some white beads. White beads are 8 in numbers. If a bead is taken from it, the probability of it being white is `1/3`
a) How many beads are there in the bag?
b) What is the probability of it being black?

A box contains 10 black beads and 15 white beads Another box contains 11 black beads and 17 white beads Without looking, a bead is drawn from each box i) What is the probability of getting a black bead from the first box? ii) What is the probability of getting a black bead from the second box? iii) Which box give more chance to get a white bead Why?

A box contains 6 red beads and 5 white beads. Another box contains 8 red beads and 4 white beads. If one bead is taken from each box, then:What is the probability that both beads are white?

A box contains 6 black and 4 white balls If a ball is taken from it, what is the probability of it being black? And the probability of it being white?

A box contains 6 red beads and 5 white beads. Another box contains 8 red beads and 4 white beads. If one bead is taken from each box, then: What is the probability of both beads being red?

A box contains 6 red beads and 5 white beads. Another box contains 8 red beads and 4 white beads. If one bead is taken from each box, then: What is the probability of getting at least one red bead?

A box contains 6 red beads and 5 white beads. Another box contains 8 red beads and 4 white beads. If one bead is taken from each box, then: What is the number of possible pairs?

A bag contains 9 balls of which 4 are red,3 are white,and 2 are green. If a ball is drawn at random,then, Calculate the probability that it is not white.

A bag contains some red and green balls If we take a ball from it, without looking the probability of getting a red ball is '1/4' a) What is the total number of balls, if there are 8 red balls? b) What is the probability that a ball taken is green? c) Find the sum of both the probabilities d) From a box containing some red balls and some blue balls the probability of getting a redball is ' a/ b' What is the probability of getting a blue ball?

A box contains beads of different colors There are total 200 beads in it One bead is taken at random The probability that it is blue is 0.98 Then, a) How many blue beads are there in the box? b) Some blue beads are removed from the box Now probability of blue bead becomes 0.96 So how many blue beads are removed?

In a bag there were'3 white balls and 5 black balls.From this one ball is taken,then :What is the probability of being white ball?
