What is the probability of drawing a red ball second?
1/5
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 of getting 9 in a single throw of a dice?
The probability of getting 9 as the sum when 2 dice are thrown is 1/9.
What is the probability of getting a red and white ball?
Therefore the probability of getting a red ball or a white ball is 4/5.
What is the probability of getting nine or ten on a single throw of two dice?
7/36
∴ The probability of getting a 9 or 10 on single throw of 2 dice is 7/36.
What is the probability of drawing a red on the first?
On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue.
What is the probability of getting a white ball in probability?
Distribute the balls (all of them) into the bowls to maximize the chance of picking a white ball. Explanation: First, let us assume that we divided the balls into jars equally so each jar will contain 50 balls. Therefore, probability of getting white ball becomes 1/2*1 + 1/2*49/99 which is approximately 3/4.
How do you find the probability of two balls of the same?
With conditional probability, you could formulate it this way: P (2 balls of the same color) = P (2 balls are white OR 2 balls are red) = P (2 balls are white) + P (2 balls are red) [since the two conditions are mutually exclusive]
How many balls do you need to pick a white ball?
You have 50 white balls and 50 black balls. After you place the balls in the bowls, a random ball will be picked from a random bowl. Distribute the balls (all of them) into the bowls to maximize the chance of picking a white ball.
