What does thrice as many red balls as green balls means?
Thrice means three times as many. If you have two green balls, it would mean you have six red balls.
3 red balls and 2 blue balls are in a bag what is the probability that both chosen will be red?
Assuming that you're only drawing two balls out of the bag, your chance of getting two reds would be 3/5 * 2/4 = 3/10, or 30%
How many syllables in the word hamster?
Hamster has two syllables in it.
What is the probability of having 2 red balls when chosen in random from a container has 2 red balls 4 green balls and 2 yellow balls?
1/4 chance
A bag contains 5 balls two balls are drawn at a random and found to be red what is the probability that all balls are red?
The probability that all balls are red is 0.50 or 50%.EXPLANATIONSuppose there are 4 boxes with 5 balls each.Box A has 2 red balls.Box B has 3 red balls.Box C has 4 red balls.Box D has 5 red balls.The probability of drawing at random 2 red balls for each box is:Box A; P(2 red balls) = (2/5)∙(1/4) = 2/20 = 1/10Box B; P(2 red balls) = (3/5)∙(2/4) = 6/20 = 3/10Box C; P(2 red balls) = (4/5)∙(3/4) = 12/20 = 6/10Box D; P(2 red balls) = (5/5)∙(4/4) = 20/20 = 10/10Now, suppose we do the drawing of 2 balls experiment 10 times on each boxgiving a total of 40 experiments. The probabilities calculated above are the"expected" results, that is; out of the 40 experiments (drawing of 2 balls), twored balls resulted:1 time came from box A3 times from box B6 times from box C10 times from box DNotice that from the 40 experiments, 20 result in 2 red balls.From here we have that when drawing 2 red balls the probability that it camefrom a box containing 2 red balls (box A), 3 red balls (box B), 4 red balls (box C)or 5 red balls is:P(A) = 1/20 = 0.05 = 5%P(B) = 3/20 = 0.15 = 15%P(C) = 6/20 = 0.30 = 30%P(D) = 10/20 = 0.50 = 50%
