What is the probability that the ball is either green or red?

What is the probability that the ball is either green or red?

There are 12 possible balls you can draw so the denominator will be 12, there are 4 red balls and 3 green balls, so there are 7 balls that fit the requirement of being either red or green. The probability of drawing either a red or a green ball is 7/12.

How many green balls are there in a bag which contains the number of yellow balls?

Total number of balls in bag B is 75. In bag C, the ratio of number of green colored balls and number of black colored balls is 7:5 Total number of green and black colored balls is 36, If one ball is picked at random then the probability of getting one yellow ball is 713.

How do you write probability in math?

The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A is often written as P ( A ) P(A) P(A)P, left parenthesis, A, right parenthesis.

How many green balls are there in the bag which contains the number?

The total number of balls is 60. There are four times as many red balls as green balls and 6 more blue balls than green balls.

What is the minimum number of balls we have to choose to ensure we get 8 balls of the same color?

Hence the minimum number of balls that would ensure that 8 balls of the same color has been pulled out is 29.

What is the probability of red balls?

a) a red ball Therefore the probability of getting a red ball is 9/20. Therefore the probability of getting a white ball is 7/20.

What is the probability that the balls drawn contain different colors?

A bag contain 2 red balls, 6 yellow balls and 4 green balls. If 3 balls are drawn randomly, then what is the probability that the balls drawn contain balls of different colors? = 48. = 12 / 55. A bag contain 2 red balls, 6 yellow balls and 4 green balls.

How many red and green balls are in a bag?

It really is! A bag contains 5 red balls, 6 yellow balls and 3 green balls. If two balls are picked at random, what is the probability that either both are red or both are green in colour? A bag contains 5 red balls, 6 yellow balls and 3 0green balls.

How many balls are there in a bag of balls?

Initially, there are (3 + 4 + 5) = 12 balls in the bag. Now, two types of draw can be done. Ways of drawing 1 red ball out of 3 red balls = (3C1) = 3. Ways of drawing 1 yellow ball out of 5 yellow balls = (5C1) = 5.

What is the required probability of 2 balls from a jar?

Thus, the required probability = (120 / 455) = (24 / 91) ≈ 0.2637. A jar contains 6 red balls, 3 green balls, 5 white balls, and 7 yellow balls. Two balls are chosen from the jar, with replacement.
