A challenge!

Let's do a multinomial experiment i.e. there are \(m\) no. of possibilities on each trial and we do \(n\) number of trials.

Moreover, the probability of getting a particular possibility at \(i\)th trial also varies, each differently, like \(a_k(i), 1 \le k \le m\)

What is the expected number of times of getting a particular possibility (let's say the one with index 1)?

The answer is \(\displaystyle \sum_{i=1}^n {a_k(i)}\) for the \(k\)th possibility. Kartik Sharma · 1 week, 4 days ago
