binomial and hypergeometric probability distributions:
from a box of 12 flares, four are selected at random. If the box contains four flares that do no work:
a. what is the probability that all four will not work?
b. what is the probability that, at most, two will not work?
c. of the four flares selected, how many would you expect to not work?
probability distribution for discrete random variables:
Jason has designed a game where if you roll a prime number with two six-sided dice, you receive twice the amount of your roll, but if you roll a composite number (not prime), you must must pay the value of the roll.
a. what is the expected value [E(x)] per roll?
b. is this game fair? explain.
Thanks for the help everyone
