Probability assistance for a medal, anyone?
Suppose you select 2 letters at random from the word compute. Find each probability.
P(2 vowels)
Side note: In the video I watched on this topic, the guy used a calculator that supported nCr, but I cannot find one that can solve this problem.

Best ResponseYou've already chosen the best response.0There are \(7\) letters you can choose from the word "compute". \(3\) of these are vowels (o,u,e). There are \(\dbinom72={}_7C_{2}=\dfrac{7!}{2!(72)!}\) ways of choosing any \(2\) letters, and \(\dbinom32\times\dbinom40=\dfrac{3!}{2!(32)!}\times1\) ways of choosing two vowels. So, \[P(\text{2 vowels})=\frac{\dbinom32}{\dbinom72}\]
