What is the probability of getting two black balls?
Total, there are 10 balls, and we’re choosing 2. Then the probability of choosing 2 black balls simultaneously is 5C2⋅5C010C2=10⋅145=29.
What is the probability of drawing a white ball from a bag?
So, probability will be 3/7.
How do you find conditional probability?
Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome. Conditional probability is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding, or conditional, event.
What is the probability that 2 balls drawn are white and blue?
A bag consists of 3 red balls, 6 white balls and 7 blue balls. What is the probability that 2 balls drawn are white and blue? P (White & Blue) = P (event 1) + P (event 2) = 7/40 + 7/40 = 7/20 = 0.35 Since both are dependent i.e the the use of ‘and’ in the question means the two events must be multiplied
How many red and white balls are in the bag?
A bag contains 6 red balls and 7 white balls. Another bag contains 5 red balls and 3 white balls. One ball is selected from each. Find the probability that one ball is red and one is white? Bag 1 contains 6 red and 7 white balls. Bag 2 contains 5 red and 3 white balls. Bag 2 contains 8 balls. 1. Probability of drawing a red ball from b
How many balls are there in a bag of cards?
A bag contains 7 white, 5 black and 4 red balls. If two balls are drawn at random, find the probability that both the balls are of the same colour. Was this answer helpful?
What are the odds of the first black ball being drawn?
Similarly, the odds are 7 out of 18 for first black ball, and 6 of 17 second black ball. The combined probability is (7/18)* (6/17)=0.137. A bag contains 7 white and 3 black balls. 3 balls are drawn at random.
