Answer:
The probability is 0.136125
Step-by-step explanation:
45% are in favor of the project, the probability of selecting someone in favor of the project will be 45/100 = 0.45
The probability of selecting someone not in favor of the project = 1 - probability of selecting someone in favor of project = 1-0.45 = 0.55
Now we have 3 people to be chosen at random with exactly one of them favoring the new building project. This means two of them will not favor the building project
Thus the probability here is = the probability of favoring * the probability of not favoring * the probability of not favoring
= 0.45 * 0.55 * 0.55 = 0.136125
Answer:
68/.75
Expand the right side:
Notice that 98 = 2 * 7 * 7, so we have 
and 
.
Then
and
Answer:
75
Step-by-step explanation:
at the top it says f(1)=25 which is 1 times f = 25 therefore f = 25
