First the common denominator has to be 6. So to get to 6 you multiply the 2 by 3 and the numerator by 3 giving 3 over 6 then you multiply 3 times 2 to get to 6 so the following fraction is 2 over 6. So when u add the two together it gives you 5 6ths

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
Answer:
