Probability

Well, in a deck of cards, there's 2, 4, 6, 8, and 10, so that's five cards. Take those five cards and multiply it by four, because there's four different suits (clubs, diamonds, spades, and hearts.) This gives you 20, out of 52 cards, or a 20/52 chance. You can reduce this by dividing by 4, to get a 4/13 chance. You can use a calculator to divide that out and find the percentage answer, which is 38.5 percent.

If you include the two jokers, then you have a 20/54 chance of drawing an even number, which works out to a 37 percent chance.

It is 0.8

It is a discrete random variable.

1/4

It is 3/4.

the likelihood that something will happen

Probablity of picking up 3 vowels from the word MATHEMATICS Each of the letters in the word MATHEMATICS is on a letter tile in a bag

50 percent

yes. the probability of winning the dollar increases from 1\3to 2\3 by switching.

30 maybe but i say 35 or 31

about 23.9

A particular fruit's weights are normally distributed, with a mean of 760 grams and a standard deviation of 15 grams. If you pick one fruit at random, what is the probability that it will weigh between 722 grams and 746 grams-----A particular fruit's weights are normally distributed, with a mean of 567 grams and a standard deviation of 25 grams.

Think, if there are A, E, I, O, U, and couting Y, there are 6 vowels. there are 26 letters. So the answer is 6 over 26 and then you simplify it to 3 over 13.

There are 10 letters is the word JOURNALISM. Since they are all different, the number of ways you can arrange them is simply the number of permutations of 10 things taken 10 at a time, or 10 factorial, or 3,628,800.

7. A bag of marbles contains 13 marbles. 5 Blue, 3 Yellow, 4 Green and 1 Red. Leave all answers as a ratio in lowest terms. 18 points

On a single draw, what is the probability of drawing a yellow marble?

What is the probability of not drawing a yellow marble?

What are the odds in favor of drawing a blue marble?

What is the probability of drawing a red or yellow marble?

What is the probability of drawing a purple marble?

If you had to bet on drawing a marble of a certain color what color would you not choose?

The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.

Provided the random variable can take only finitely many, equally spaced values, you can write one in terms of the other. For details see the paper by Ales Cerny entitled "Introduction to Fast Fourier Transform in finance".

With replacement, the odds of the second extraction do not change after the first, because of independence of the two extractions. Hence, the probability of extracting two reds is (3/5)*(3/5), the probability of two greens is (2/5)*(2/5) and that of one red and one green is 2*(3/5)*(2/5).

Since there are 2 outcomes for a coin toss, and you will toss the coin 3 times the number of outcomes are 23 or 8. Since H-T-H can occur only 1 way, the probability of the H-T-H sequence is 1/8.

There is no probability. Sorry.

Homogeneous refers to groups composed of parts or elements that are all of the same kind or nature. In stratified sampling, a population which is composed of diverse groupings is subdivided into two or more groups so that the diversity is decreased in the subgroups. For example, if the total population is composed of males and females, then stratification into subgroups of male and female will result in strata that are of the same kind with respect to the classification variable gender: i.e, the strata are homogeneous. Other classification variables or combinations of classification variables may be used to improve homogeneity.

The mean and standard deviation often go together because they both describe different but complementary things about a distribution of data. The mean can tell you where the center of the distribution is and the standard deviation can tell you how much the data is spread around the mean.

IF YOU HAVE ONE GAME, YOU HAVE A POSIBILITY OF 3 OUTCOMES, IF YOU HAVE 2 GAMES IT GO'S UP TO 9 POSIBILE OUTCOMES.

FIRST ANSWER 1X3=3

SECOND IS 3X3=9

FOR 10 GAMES IT IS 3X3 TEN TIMES

3X3X3X3X3X3X3X3X3X3=59,049

POSSIBLE COMBINATIONS

(I THINK)HA HA

For each question the student has a 50% chance of answering right.

We can express this as a fraction of 1 (1 being 100%): 1/2, i.e. 0.5

There are 5 questions, so the answer will be:

0.5*0.5*0.5*0.5*0.5=0.5^5=0.03125

or 3.125%
