Probability

On one random draw, the probability is 2/13.

he possibility of that outcome.

Apart from the fact that he was born on 4 May 1655, almost nothing is known about his early life, let alone his childhood.

i dont no

Yes.

They are called combination locks because that is the general, conventional term used. Trying to call them permutation locks is mixing different areas of usage together and that is not valid.

If they were not then they would not be called identical twins!

There is insufficient information in the question to answer it correctly. Please restate the question.

About 9000 planes fly at the same moment

It is 6/36 = 1/6

On a six sided die; 1/6

The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling a 3 is 1 in 6, or about 0.1667, but the experimental probability changes every time you run the experiment

Different examinations have different thresholds for A grades.

2 in 52, or 1 in 26, or about 0.03846.

Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.

At least the numbers work out that way assuming they keep having kittens and none of them die, etc. If each litter has 2.8 surviving offspring and each female cat has two litters per year. (Cat litters average about five and they can have a litter every three months so these numbers could be substantially higher.)

Year 1: (two cats litter at time zero, time six months and 12 months): 12 offspring

Year 2: 1/2 of all cats in Year 1 had 2.8 kittens at 18 and 24 months): 54

Year 3: 316

Year 4: 1819

Year 5: 10,479

Year 6: 60,360

Year 7: 347,674

Year 8: 2,002,600

Year 9: 11,534,979

Year 10:66,441,480

Total: 80,399,772

If you assume each litter has 4 kittens, the number is 6.9 billion. Even if each litter is two kittens, the total is still around two million. This is a pretty compelling case for fixing your cats.

A cricket ball is required to be between 155.9g and 163g.

If you mean roll 2 dice and spin a 2 colour spinner, there would be a total of 72 outcomes.

P(Heart) = 13/52

P(King) = 4/52

P(Heart and a king)= 1/52

P(Heart or a king)=P(Heart) + P(King) - P(Heart and a king)

=13/52+4/52-1/52

=16/52

There are 2,598,960 possible five-card hands. There are 4 combinations of royal flushes in 5 cards. Therefore, the odds are 649,739:1.

There are 20,358,520 possible six-card hands. There are 188 combos of royal flushes in 6 cards. Therefore, the odds are 108,290:1.

The answer depends on how many cards are dealt to you. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
