We just need to count the number of outcomes that have exactly one even number. The total number of outcomes is 36. We see that from the first row, the number of outcomes that qualify are 3: 1-2, 1-4, 1-6 (out of the 6 total outcomes). For the 2nd row, again there are 3: 2-1, 2-3, 2-5. It is obvious by now that for any row, whether the number is even or odd, there are 3 outcomes on that row that correspond to rolling exactly one even number. Hence, there are in total 6*3=18 favorable outcomes.
Answer:
11.1d + 3.2h - 15
Step-by-step explanation:
=3/2+ 9/4+ 2/2
=1.5+ 2.25+ 1

Answer:
Formula is 132 - 8n, and there are 52 windows on 10th floor.
Step-by-step explanation:
difference = 116-124 = -8 ( 8 less windows for every floor you go up)
the first fllor has 124 windows
Formula:
= 132 - 8n
10th Floor:
You can find 15 DVDs.
165 divided by 11 = 15
