Answer:
7.2 times
Step-by-step explanation:
There are 36 possible outcomes when rolling a die twice and adding the results. The outcomes for which the sum is 6 are:
Sum = 6: {1,5; 2,4; 3,3; 4,2; 5,1}
Therefore there is a 5 in 36 chance that the sum will be 6.
The expected number of trials to achieve that result is given by:
On average, it would take 7.2 trials to achieve a sum of 6.
The correct answer is 17.01
