## Help if you please...

The manufacturer of Pars (chocolate) Bars is running a marketing promotion. As part of this promotion, 10% of Pars Bars wrappers display a token which entitles the purchaser to a free Pars Bar. Joe plans to buy 12 Pars Bars.

What is

(a) the probability distribution of the number of free Pars Bars that Joe can win?

(b) the probability that Joe wins at least two free Pars Bars?

(c) the most likely number of free Pars Bars Joe can win?

regards.
