Question 874036: It is known that when a particular 4-sided die is rolled a 1 occurs 30% of the time, a 2 occurs 20% of the time, a 3 occurs 25.9% of the time, and a 4 occurs 23.1% of the time. Any help would be greatly appreciated.
a) If the die is rolled 17 times, what is the probability that an odd number occurs exactly 9 times?
b) What is the expected value of a single roll of the die?
