A bag contains 6 red marbles, 5 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probabi
SVETLANKA909090 [29]

Answer: 5.8%

Step-by-step explanation:

In this situation there is no replacement so we have to mulitply the probablilty of the first,second, and third marble being green. First marble has a 8/19 probablilty of being selected because 19 total marbles in the bag and 8 green marbles. the next marble will have a 7/18 probabililty because now only 18 marble are in the bag and we are assuming we selected a green marble on our first draw. Same thing with the last green marble it would be 6/17 because there would be 17 marbles in the bag and 6 green ones left assuming we got the first 2

so 8/19*7/18*6/17=

56/969=

0.05779

5.77%

5.8%

A student is taking a​ multiple-choice exam in which each question has two choices. Assuming that she has no knowledge of the co
seraphim [82]

Answer: Hi!

So if in the box there are 2 balls and she chose one at random, then she had a 0.5 probability of chose each ball, and then she has a 0.5 probability of choosing the ball that is associated to the correct answer, then she has a 0.5 of getting each answer correct.

Now she has 4 questions, then the probability for getting all of them correct is the product of the probabilities for each one; this is:

0.5*0.5*0.5*0.5 = 0.0625

multiplied by 100%, we get a 6.25% of getting the four answers correct using this method.
