Its something ive been asking myself. Im studying physics, but I havent studied anything related to probability since before high school(adsbygoogle = window.adsbygoogle || []).push({});

I mean, for example, the chance of getting tails after one throw is 50%, after two throws 75%, after three throws 87,5% and so on..... (right?)

Say, you roll a dice 6 times. You trying to get a number, say, 2.

What is the chance of getting a single 2 after the six rolls?

What is the chance of getting two 2s after the six rolls?

I just want to know how probability stacks up, and if there's a formula to determine it.

Now for something a little more complicated.

Imagine theres some woman giving away candy to children.

now say each kid gets five chances to pick from a bag with one sweet and a changing number pieces of coal. If you pick up the sweet, she'll put another one for you to pick up the next time. (So theres a chance youll end up with five sweets)

1st time

50 sweet

2nd time

40 sweets

3rd time

35 sweets

4 time

30 sweets

5th time

20 sweets

I made up the problems, so feel free to change the data, or not even comment about them.

I just want to get a decent grasp on it
