Question

Use the following values instead of those found in your book.
(1) 1 success in 3 trials with p = 0.2:

(2) 1 success in 3 trials with p = 0.6:

(3) 3 successes in 5 trials with p = [ 1/5]:

Answer 1

You're giving me the probabilities for certain events, but I don't see any question where I can apply those probabilities too. Could it be a problem that's in your book? Just my guess, since the first sentence also says:

Use the following values instead of those found in your book.

It may be helpful for you to know the distribution of the data you're working with. For example, the usual distribution for an outcome with exactly 2 possibilities, general follows a binary distribution, and the probability of each 'trial' is 0.5.

That distribution also makes a few assumptions: The key conditions are a fixed number of trials (𝑛), two possible outcomes per trial, a constant probability of success (𝑝) for each trial, and that each trial is independent of the others.

I hope that's helpful, because I don't really know what your question is, because I don't see a 'problem' in your message to spply those different probabilities too. Thanks, Marla
