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%

A bag contains 3 red balls and 2 blue balls a ball is taken at random from the bag and then put back what is the probability that both balls are red?
3c2+2c2+3c1 2c1 --------------- 7c2. I have done it this way. 3C2 means that the both balls would be green 2C2 both would be red and 3C1 and 2C1 because both the balls can be red and green.
If A box contains three black balls and four gold balls Two balls are randomly drawn in succession from the box If there is no replacement what is the probability that both balls are black?
(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.
Five women live together in an apartment Two have blue eyes If two of the women are chosen at random what is the probability that they both have blue eyes?
well lets look at the probability on your first pick you will get a blue eyed girl 2 have blue out of 5, so yo uhave a 2/5 chance, or 40% on your second pick, there are 4 girls left, and one of them will have blue eyes now 1 have blue out of 4, so 1/4 or 25% so you multiply the two probabilities to get your final sequential probability 2/5 * 1/4 find a common denominattor, for this we will use 20 8/20 * 5/20 = 40/400 simplify it you get 1/10 0.10, or 10% chance
There are 4 red marbles and 6 blue marbles in a bag. if Sarah pulls out one marble then another what is the probability that both marbles in her hand will be red?
The probability is 2/15.
What do experimental probability and theoretical probability have in common?
They are both measures of probability.

Two students are chosen at random from a class of 30 what is the probability that both you and your best friend are chosen?
The probability of this is based heavily on whether or not said best friend is even in the class. If both are in, it's a 1/870 chance.Ê
What is the probability of drawing a red or a 5 ball out of a bag that has 4 red balls numbered 1 through 4 and 3 blue balls numbered 3 through 5?
There are 7 balls in total.4 are red and 1 is the blue "5" ball. Thus there are five balls out of the seven which meet the criteria and therefore the odds must be 5/7.The probabilities are mutually exclusive (i.e. you can not both draw a red ball and the "5" ball at the same time as the "5" is blue) so you just add the probabilities of each together.Probability of drawing a red ball = 4/7 (4 of the 7 balls are red)Probability of drawing the "5" ball = 1/7 (1 of the 7 balls is the "5" ball)Overall probability = 4/7 + 1/7 = 5/7
A box contains 7 red balls and 11 black balls two balls are taken out one after the other without replacement what is the probability that both balls are black?
11/18 x 10/17 = .359
If a bag1 have 12 balls including 4 black balls and bag2 have 12 balls including 2 black ball how many black ball need to put in bag2 to make same probability of both bag?
The probability of a black ball in bag 1 is 4/12 = 1/3. If you add 3 black balls to bag 2, it will contain 5 black balls out of 15: the probability of a black ball being 3/15 = 1/3.
If a box contains three blue cards and three white cards If two cards are drawn one at a time find the probability that both cards are blue if the draws are made with replacement?
The probability of drawing two blue cards froma box with 3 blue cards and 3 white cards, with replacement, is 1 in 4, or 0.25.The probability of drawing one blue card is 0.5, so the probability of drawing two is 0.5 squared, or 0.25.
Five women live together in an apartment Two have blue eyes If two of the women are chosen at random what is the probability that they both have blue eyes?
well lets look at the probability on your first pick you will get a blue eyed girl 2 have blue out of 5, so yo uhave a 2/5 chance, or 40% on your second pick, there are 4 girls left, and one of them will have blue eyes now 1 have blue out of 4, so 1/4 or 25% so you multiply the two probabilities to get your final sequential probability 2/5 * 1/4 find a common denominattor, for this we will use 20 8/20 * 5/20 = 40/400 simplify it you get 1/10 0.10, or 10% chance

If A box contains 4 blue chips and 5 black chips and 2 chips are drawn at random with replacement what is the probability that both will be blue?
Two out of nine. 2:9.
When forty three percent people wear seat belt If two people are chosen at random what is probability that both of them wear a seat belt?
About 18.5 percent thst both will have seatbelts on. (.43 x 2)
