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

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.

How many ways ten balls can be picked from a pile of red blue and white balls?

Now, 10 balls can be selected from these 47 balls in ways. …

What is the probability of selecting two red balls if the first ball drawn is returned to the jar before the second ball is drawn What if the first ball is not returned?

On your first pick, the probability is 11/16 that you choose a red ball. On the second pick, the probability is 10/15 that you choose a red ball. So 11/16*10/15 = 110/240 = 45.83\% chance of picking two red balls in a row.

What is the probability that both balls drawn are red?

In conclusion, the probability that both of the balls are red is 1/10.

What is the probability of the first ball being red?

5/8
Each ball is equally likely to be drawn. So the probability that the first ball drawn is red is 5/8.

What is the probability that the second ball is red given that the first ball is red?

We start with 12 balls, 7 of them are red. If the first ball we choose is red, then there are 11 balls left in the bag, and 6 of them are red. So the probability that the second ball is red, given that the first ball is red, is 6/11.

What is the probability of drawing two red balls or two?

“Drawing two red balls OR two blue balls results in a probability of 0.44.” The “OR” separates our calculation into two parts: Drawing two red balls (i.e drawing a red from the first urn AND a red from the second.) Drawing two blue balls (i.e. drawing a blue from the first AND a blue from the second.

What is the probability of picking a red ball in blackjack?

What is the probability of picking a blue or green ball?

2) There is only one black ball in the box so the probability is 1/10 or 10\%. 3) There are 8 balls that are not blue, so the probability of picking a ball that’s not blue is 8/10 or 80\%. This makes sense because most balls are not blue in colour. 4) The probability of picking a blue ball is 2/10 and the probability of picking a green ball is 3/10.
