What kind of probability is this?  It has a particular name.  What is n?  What is p?

idk... im learning binomial experiments...

mathmale · Answer

You're learning binomial probability.  Yes.  this is a problem in binomial probability.

n is the number of trials, and p is the probability of "success" on any trial (same prob. for all trials).

What next?  What do examples in your notes show?

mathmale · Answer

You could either calculate binomial probability or use a table of values or use your calculator (e. g., a TI-84) to calculate the desired probability.  Your choice?
