Susan rolls 4 six-sided dice at once to win a bet with her neighbour Jeff. If all 4 dice return the same number after only one roll, Susan wins her bet. What is the probability that Susan LOSES the bet?  Choose the most appropriate option.
A) Less than 50%
B) Between 50% and 70%
C) Between 70% and 90%
D) Between 90% and 99%
E) Greater than 99%
The acceptable rolls are all of the Quad-tuples: 1111, 2222, 3333, 4444, 5555, 6666. Thus there are six possibilities. The four dice can roll 6*6*6*6 (6^4) number of ways. The probability that Susan wins the bet is: 6/6^4 = 1/6^3 = 0.0046 = 0.46%.   Therefore probability that Susan loses is 1 - probability of Susan winning:   1 - 0.46% = 99.5% &gt; 99%   Answer: Greater than 99%.
