- Five faces of a fair die are painted black, and one face is painted white. The die is rolled six times. Which of the following results is more likely?
a. Black side up on five of the rolls; white side up on the other roll
b. Black side up on all six rolls
c. a and b are equally likely
Solution
probability of black face=5/6,, probability of white face=1/6
a.Probability of five times black fce and 1 time white face=6C5(5/6)5(1/6)=(5/6)5?
b. Probability of Black side up on all six rolls=6C6(5/6)6=(5/6)6?
a and b are not equal
