Ok, so, say we have a magic coin. The coin has a 30% chance to land heads up, a 30% chance to land tails up, and a 40% chance to land on its edge....
Or, a non-fair die that has a 30/30/40 chance of landing on 1,2 or 3 respectively...
If you flip the "Coin" 2 times, what are the chances you will get heads at least once? What are the chances you will get heads both times?
Either way, I was looking onto using the binomial distribution, but this doesn't fit. The criteria are (obviously) that the results:
• are dichotomous (nope)
• are mutually exclusive (yep)
• are independent and (yep)
• are randomly selected (yep)
So.... I was planning on using the equation
P(m of k in s from n) =
with m=1, k=2, s=30 & n=100
Unfortunately, i have no idea how to actually solve this equation as I am not in any sort of math classes. I know how to do basic algebra and geometry, but I have no idea what to do with a comma in an equation. Can someone please give me a crash course in how to actually use this equation.
