Its something I've been asking myself. I am studying physics, but I haven't studied anything related to probability since before high school
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 there's 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 there's 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
