Answer:
0.28
Step-by-step explanation:
If the probability that the student does take statistics is 0.72, then it must mean that the rest of the students will not take statistics.
1 - 0.72 = 0.28
0.28 will be the probability that the student does not take statistics.
If you distribute, then you get -10x+7.5
Note how -2.5 times 4x = -10x and how -2.5 times -3 = 7.5
The idea is that you multiply the outer term (-2.5) by each term inside
2
the correct answer is 260
