Step-by-step explanation:
Answer: D)0.205
Step-by-step explanation:
In binomial distribution, the probability of getting success in x trials is given by :-
, where n is the total number of trials , p is the probability of getting success in each trial .
Given : The probability that a component will fail is 0.2.
Let x be the number of components will stop working.
i.e. p=0.2
n=12
Since The machine will stop working if more than three components fail.
Then, the probability that the machine will stop working will be :-
Hence, the probability that the machine will stop working is 0.205.
Thus , the correct answer is D)0.205
Answer:
x=10
Step-by-step explanation:
The left side −16 is equal to the right side −16, which means that the given statement is always true.
Answer:
A
Step-by-step explanation:
Subtract 1 from both sides and divide by 2. This will leave you with x=-2 which is the simplified form of the equation.
