12^3 / 12^7
Cancel out the common factor:
Multiply the numerator by 1:
12^3 * 1 / 12^7
Factor 12^3 out of the denominator to get:
12^3 * 1 / 12^3 * 12^4
Now cancel the common factor to get:
1/12^4
(n / 10) + 15
The quotient is the result of division between two numbers

It’s biased because he is asking people who left a country concert and usually people who go to concerts go because it’s the type of music that they like, so the chances of someone saying they like a different kind of music probably won’t happen.
Answer:
P(X=3cars) = 0.052
P(X>3 cars) = 0.00638
Step-by-step explanation:
In total there are 7 cars per hour.
Using formulae for geometric Probability
P(X=3) = (7^3×e-7)/3! = 0.0521
P(X>3cars) = (7^2× e-7)/2! =
P(X>3) = 0.0128/2×1 =0.00638
