Answer:
The answer is 
Step-by-step explanation:
If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5
Thus, P(identify tap water)=0.5
The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities
- 8 of 9 people identified correctly or
- 9 of 9 people identified correctly
Since P(identify tap water)=0.5 each probabilities are the same and equal to
=
So we have 
=
These tables have infinitely many values, but the simplest ones would be:
a) x|y
3|5
6|10
9|15
b) x|y
2|1
4|2
6|3

Answer:
6m²
Step-by-step explanation:
Because the question asks for the area of a face but it doesn't indicate which face then it can be any of the faces.
2m x 3m = 6m²
2m x 4m = 8m²
3m x 4m = 12m²
In your case one of the possible answers is 6m² - so that is the one they are looking for.
