Answer:
25% probability that all three residents will choose the same plumbe
Step-by-step explanation:
For each resident, there are only two possible outcomes. Either they choose the first plumbe, or they choose the second. The plumbers are chosen independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Each resident randomly chooses one of the two plumbers.
This means that 
Three residents:
This means that 
What is the probability that all three residents will choose the same plumb
This is P(X = 0)(all choose the second pumble) or P(X = 3)(all choose the first pumble). So

25% probability that all three residents will choose the same plumbe

Answer:
x=-3 y=17 (-3;17)
Step-by-step explanation:
-3x+8-y=0
-5x+2-y=0
-2x-6=0
So: x=-3
While....by substituting: y=17
Answer:
x=14
Step-by-step explanation:
First bring the 6 to the other side and then bring the 4x to the other side to have 5x-4x=6+8 and combine the like terms and x equals 14.
