a jar contains 7 blue cubes 4 blue spheres

What is the probability of obtaining a number less than 2 or greater than 7 in a single spin? 3/16 7. A spinner is numbered from 1 through 10 with each number equally likely to occur. A bag contains 8 red marbles, 4 white marbles, and 5 blue marbles. In how many ways can 3 singers be selected from 5 who came to an audition? 0 5. In how many more orders can Verne line up his books than Jenny? 7 3. Jenny has 4 English books to line up on a shelf. Verne has 6 math books to line up on a shelf. How many routes are there from Ruth Ann's school to her home with a stop at the library? 696 2. Suppose Ruth Ann has 3 routes she can travel between the school to the library, and 5 routes from the library to her home. Random, what is the probability that the object is green or a cube? 15 1. A jar contains 7 blue cubes, 4 blue spheres, 5 green cubes, and 6 green spheres. Suppose S and T are mutually exclusive events. Which events are mutually exclusive? 42% 4. P(Q) = 0.41, P(R) = 0.44 Rolling an even number and an odd number 3. ANSWERĪll questions are answered and carefully explained.Taking two marbles from a box without replacing the first marble 1. (3) In this case, you select from 16 non-red marbles so the probability is THEREFORE, the final probability in this case is P = 0.3831 (approx. The numerator in the formula is the number of all possible 5-marble subsets, containing EXACTLY 2 red marbles. It is so called 'the set of all possible events' in this problem. In other words, it is the number of all possible 5-marble subsets of the given set of 26 marbles. The denominator is the number of all combinations of 26 marbles taken 5 at a time.

(2) In this case, the probability is THIS FRACTION (1) You INCORRECTLY calculated the answer to this question. This to be similar to the complement of the first question, but that does not give th right answer, (3) What is the probability that none of the marbles are red? I know that the 'exactly' part is important I just don't know what to do in that case.

I assumed it just was (10/36)*(9/35) but that is not the case. (2) What is the probability that exactly two of the marbles are red? (1) What is the probability that all the marbles are red? You draw 5 marbles out at random, without replacement. You can put this solution on YOUR website!Ī bag contains 10 red marbles, 8 white marbles, and 8 blue marbles. This to be similar to the complement of the first question, but that does not give th right answer, I tried 1-((10/36)*(9/35)*(8/34)*(7/33)*(6/32)) which is incorrect. The probability of picking no red marbles is What is the probability that none of the marbles are red? The probability that exactly two of the marbles are red is

What is the probability that exactly two of the marbles are red? The probability that all the marbles are red is What is the probability that all the marbles are red?
