Probability

The probability of doing so, eventually, is 1. In a single random draw it is 1/52.

If the die is fair, the probability is 1/6.

If the numbers are 1 to 6, there are three prime numbers in that range, a probability of 50%.

P(A)=1-(A)

Assuming a standard 6-sided die with sides numbered {1, 2, 3, 4, 5, 6}, then:

Number of successes = 1

Total number of outcomes = 6

→ pr(2) = 1/6

• There are 475 people total
• 300 are male so 175 are female (assuming they all identify as male or female)
• 135 males like fried food
• 270 people total do not like fried food
• 105 females do not like fried food
• 175 - 105 = 70 females do like fried food
• 270 - 105 = 165 males do not like fried food

a.) Probability that the person is female is 175/475 = ~37%

b.) Probability that the person is female and likes fried food is 70/475 = ~15%

c.) Probability that the person is female or does not like fried food is (175 + 165) / 475 = 85%

In essence there are only 3 possibilities:

RRY

RYR

YRR

The sum of the odds of these three things is the possibility of one of them happening. The order does matter in this, because which one you draw first affects the odds of which one you draw second in this scenario.

There's 20 balls to begin with, and each time we remove a ball we're decreasing the total number, so the odds break down like this:

RRY:

12/20 * 11/19 * 8/18

RYR:

12/20 * 8/19 * 11/18

YRR:

8/20 * 12/19 * 11/18

Because of the specific circumstances the odds of each are actually the same (because we're decreasing the total pool and the individual pools at the same rate in all three, essentially they're the same numbers in different orders). Each has a roughly 15.2% chance, and adding those odds together gives us the odds of one of them happening (but it doesn't matter which one).

Totaling to a roughly 46.2% chance of drawing some combination of the three.

For comparison, there's a 19.2% chance that they come up as RRR, and a mere 4.9% chance that they come up YYY. The odds of two yellows and a red, meanwhile is about 29.4. Note that, because of my rounding this only totals out to 99.7%, but you get the picture. If you need the odds to a more specific decimal point, you can plug in the numbers and get the full totals.

Birthdays are not uniformly distributed over the year. Also, if you were born on 29 February, for example, the probability would be much smaller. Ignoring these two factors, the probability is 0.0082

No. A probability means, how likely it is for something to happen. An observation of SEVERAL similar events can give you a good ESTIMATE of the probability.

If you randomly pick a card from a standard deck of cards, that probability will be 1/4, since 1/4 of the cards are heart.

Such an outlook is categoriezed as a slight risk.

Tornado activty in such an instance can vary quite a bit as such outlooks come with a high degree of uncertainty. To a large degree what is likely to happen depends on the area covered. Such outlooks often indicate a few tornadoes, some of which may be strong, can occur, especially if there is a hatched area included. In some cases a moderate tornado outbreak may occur. Sometimes there is potential for one or two violent tornadoes. Again, though, as there is a high degree of undertainy in many cases, sometimes the forecast tornadoes fail to develop.

A blow to the head can cause a brain aneurysm, but this cause is only 1% of all cases, so it's unlikely.

No. The probability cannot be negative.

Clearly, it is necessary to draw at least two cards. How many are drawn? Are the cards drawn at random? Is the first replaced before drawing the second?

DJ is the short form and now general usage for Disc Jockey.

It is P or Pr or the Greek letter pi (Capital).

The probability is 3/4.

There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.
However, if you assume that children's genders are independent events then, given that the probability of a girl is approx 0.48.
