11-41.

It’s bad enough when Myriah has to do the dishes. But Myriah really hates doing the dishes several days in a row! Myriah and her mom have agreed to roll two dice. When the sum of the dice is $6$ or less, Myriah has to do the dishes. If the sum is $7$ or more, one of her parents does the dishes. Myriah wants to know how many times in the next two months she will end up doing the dishes $3$ or more days in a row. 11-41 HW eTool (CPM).

1. Run a simulation of rolling the two dice and record the sum of each roll to simulate the $60$ days ($2$ months).

See problem 11-18.

2. How often can Myriah expect to have to do the dishes $3$ or more days in a row during two months?

Answers will vary, but should be $≈ 7$-$8$ days.
