Answer:
0.04865 or 4.9%
Step-by-step explanation:
This is a binomial distribution function which is expressed as:
Where:
- p=probability of success
- x=number of successful events
- n=size of the sample
Given that p=0.03, n=12 and x=2+, the probability of a cash back is calculated as:
Hence, the probability of a cash return is 0.04865 or 4.9%
Answer:

Answer:
the equation which can be simplified as
is :-
Step-by-step explanation:
here's the solution :-

Since the average of 6 tests is 6, and we know that the average is found by dividing the total score by the number of tests, we can just multiply the average by the number of tests to find the total score. Doing this, we get 82 * 6 which simplifies to 492.
Answer:
The common difference is -1/2
Step-by-step explanation:
we know that
In an Arithmetic Sequence the difference between one term and the next is a constant and is called the common difference
we have
a1=2/3
a2=1/6
a3=-1/3
a4=-5/6
so
a2-a1=1/6-2/3=-1/2
a3-a2=-1/3-1/6=-1/2
a4-a3=-5/6-(-1/3)=-5/6+1/3=-1/2
therefore
The common difference is -1/2
