What is the probability that the first ball is red and the second ball is blue?

two out of 49
Eight forty-ninths multiplied by twelve forty-eighths is equal to two forty-ninths. Therefore, the probability that the first ball is red and the second ball is blue is two out of 49 — two forty-ninths.

What is the ratio of red to green balls?

The ratio of red balls to green balls is 4:3.

What is the probability that at least one ball is red?

149204
Thus, the probability of getting at least 1 red ball is149204. Thus, the probability of getting one ball from each colour is=417.

What is the probability the second ball is red?

1/5
If we randomly select two balls from the box: The chance of drawing a red ball on the first draw is still 2/6, but once it’s drawn there are only 5 balls remaining in the box, only one of which is red. The chance of then getting a red ball on the second draw is 1/5.

What is the probability that the first ball is red and the second is black?

15 out of 36
There are now 21 red balls, and there are still 15 black balls. This is a total of 36, and the probability of selecting a black ball now is 15 out of 36. This is the probability we are looking for. The probability that the second ball is black given that the first ball is red is 15 out of 36.

What is probability of getting a red ball?

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

What is the probability that a green ball and a red ball are drawn in succession?

1/2
If two balls are drawn in succession then the probability that one is red and other is green is. Hence, the required probability = 150/300 = 1/2.

What is the ratio of 7 4?

Expressed as a fraction, with the numerator equal to the first quantity and the denominator equal to the second, the answer would be 7/4. Two other ways of writing the ratio are 7 to 4, and 7:4.

What is the probability that there is at least one green ball?

Find probability of getting at least 1 green ball: (1420)2=(710)2=49100 is the probability of not getting a green ball in the draw hence 1−49100=51100 is the probability of getting at least 1 green ball.

What is the probability that the second ball is green?

Probability that the second ball drawn is green is now 5/8. So if you want both these outcomes to occur, it would be 4/9 AND 5/8. In other words, 4/9*5/8.

What is the probability of picking the Green and red ball?

So the probability of picking both is: 5) The probability of picking a red ball is 4/10 and the probability of picking a green ball is 3/10 and because the ball is put back in the box, the second green is also 3/10. So the probability is: Fig.5 Probability without replacement second ball out.

Why does a red ball not look red?

It cannot look red unless there is red light coming to it from the light source. And it cannot look blue because the red ball absorbs blue light. So when we ask what color an object is, the answer is not simple – it depends on what color light we are using to see the object.

What is the probability of getting the second ball as Blue?

Hence, the probability of getting the second ball as blue or the second event is 4/19. Again with the first and second event occurring, the number of possibilities left for the third event to occur is 19 – 1 = 18. And the probability of the third ball is white or the third event is 11/18.

What color does white light reflect off a red ball?

For example, if white light shines on a red ball, the ball reflects back mostly red light, and so we see red. Most of the greens and blues that are part of white light are absorbed by the ball so we cannot see them.
