What is the probability of selecting exactly two balls of the same color?
The probability that both balls are the same color is 0.44.
What is the probability of getting 2 red balls in a draw of two balls from a box containing 4 white and 3 red balls?
= 1/7.
What is the probability of having at least 1 white ball?
The probability of getting at least 1 white ball equals the sum of the probabilities of getting a white ball first and getting a white ball second. The probability of getting a white ball on the first one is 3/10. The probability of getting a white ball on the second one is 2/9.
What is the probability of drawing 2 red balls without replacement?
The total probability of getting two red balls without replacement is (1/2)*(9/19) = 9/38.
What is the probability of getting at least one red ball?
149204
Thus, the probability of getting at least 1 red ball is149204. Thus, the probability of getting one ball from each colour is=417.
How many red and green balls are in each bag?
Bag 1 contains 5 red and 3 green balls. Bag 2 contains 4 red and 6 green balls. Bag 2 contains 10 balls. 1. Probability of drawing a red ball from bag 1 and green ball from bag 2
What is the probability of picking a red ball in probability?
There are 6 red, and therefore the probability of picking a red ball is 6/14. Can be simplified to 3/7. Similarly, the probability of picking a red ball in the second bag is 7/17. So now we need to think about the problem a lil bit.
What is the probability of drawing the same ball twice?
For no reds to be drawn in 2 draws, the first draw has a half-half chance while the second draw has a lower than half chance or precisely 2 out of 5. Back to the question, the probability is 1 – 0.2 = 0.8 or 80\%. If you do a “sense” check, having half of the 6 balls are red and you can draw twice, our sense will tell us the chance is pretty high.
What is the probability of no reds being drawn in two draws?
Answering at least is always easier if trying to answer the opposite: what is the chance of no reds are drawn. For no reds to be drawn in 2 draws, the first draw has a half-half chance while the second draw has a lower than half chance or precisely 2 out of 5. Back to the question, the probability is 1 – 0.2 = 0.8 or 80\%.
