Answer:
Verified
Step-by-step explanation:
Let A matrix be in the form of
Then det(A) = ad - bc
Matrix A transposed would be in the form of:
Where we can also calculate its determinant:
det(AT) = ad - bc = det(A)
So the determinant of the nxn matrix is the same as its transposed version for 2x2 matrices

Answer:
There is a 4% probability that a customer buys three tires.
Step-by-step explanation:
We have those following percentages
60% buy four tires. This is also the probability that someone buys four tires.
22% buy two tires
14% buy fewer than two tires(one or none).
P% buy three tires
The sum of the percentages must be 100%.
So
There is a 4% probability that a customer buys three tires.
