Probability

Presumably you are asking what the chance of rolling AT LEAST one 2 is. To do this calculation we first work out the probability of NOT rolling a 2, which is 1/6.

We then calculate the probability of NOT rolling ANY 2 in 500 rolls. That is 1/6 to the power of 500.

So now that we have the probability of it NOT happening, we subtract that number from 1 to get the probability of it happening.

Pr(x) = 1 - 1/6^500

The answer is so close to 1 that it's not worth writing out decimally. Basically 0.999999... with almost 400 nines. It's virtually guaranteed that you will get at least one 2 in 500 rolls.

If your question was instead what is the chance of getting ONLY one 2 out of 500 rolls then the answer is basically the opposite - the answer is almost zero.

The simple ratio of 2 green bags and 1 blue bag is -

2 : 1

Rock and roll was distinct because it blended various musical genres, including rhythm and blues, country, and jazz, creating a fresh sound that resonated with youth culture in the 1950s. Its emphasis on electric guitars, strong backbeats, and energetic performances set it apart from previous music styles. Additionally, rock and roll challenged social norms and embraced themes of rebellion and freedom, making it a cultural movement beyond just a musical genre. This innovative fusion and cultural impact contributed to its lasting legacy.

You might have to use maths in working out costs of things. For example, if it says 20% off you would need to work out 20% of the cost to know how much to pay.

Also in cooking, working out how much in weight of the ingredients you need to use.

I find that the only maths you really need for everyday life is adding, subtracting, multiplication and divition. If you know how to apply those you're O.K. for most things.

I agree though this is really arithmetic - dealing with basic quantities of counted objects.

The question though is open-ended: what do you mean by "daily life"? Even if not a professional mathematician or physicist, as physics is largely applied maths, you may find yourself performing basic mensuration, trigonometry, algebra as applied formula manipulation, and so on.

For example, my hobbies can involve trig, co-ordinates, areas & volumes; a friend who is a central-heating installer has to know quite a few formulae in his daily trade-work.

Oh, dude, let me break it down for you. So, to get a sum of 12 with three dice, you can roll a 6, a 5, and a 1. Or, you could roll a 5, a 6, and a 1. Or a 4, a 4, and a 4. That's like... three ways. Math can be fun, right?

between 15 and 20.

Zero.

7/10

Yes

It is 0.37, approx.

It is body language for "yes".

7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability

It is: 59C7 = 341,149,446

well why can't pigs fly?

same thing!

Z-score is the x value minus the mean, all divided by the standard deviation; or z=(x-mu)/sigma. The "x" value needs to be given to answer the question.

There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information.

The factors of 20 are 1, 2, 4, 5, 10, and 20. We can take 10 and 20 off the list, because they're not on the six-sided dice.

So, 4 out of 6 sides of the dice will give us a factor of 20. That means we can expect (if the dice is fair) to get a factor of 20 about 4/6 of the time. 4/6 simplified is 2/3.

1/2 * 1/2 * 1/2 = 1/8 = 12.5%
