A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
There are 3+10+4 = 17 counters.
Of those, 3+4 = 7 are white or green
7/17 = 0.4118
41.18% probability of drawing a white counter or a green counter

12m
Step-by-step explanation:
work out the area of the rectangle then times it by 2 because the parallelogram is twice the area of the rectangle. 8 × 4.5m = 36m². 36 ×2 = 72cm². Now you do 72 ÷ 6 = 12 . the answer is 12m.
Answer:
h = 33 hours
Step-by-step explanation:
Given that,
Addison worked 6 more hours this week than last week. In total, she worked 72 hours this week and last week.
The equation is :
2h + 6 = 72
We need to find the number of hours
2h = 72 - 6
2h = 66
h = 33
Hence, Adison worked for 33 hours last week.
