Hi the context of the question has been attached, along with venn diagrams. Please answer the following questions:

a) Calculate the probability of more than 20 vehicles per minute entering the city

b) Calculate the probability of observing more than 10 vehicles per minute on road B given that there are more than 7 vehicles per minute on road B

c)Calculate the probability of observing more than 8 and 10 vehicles per hour on road A and road B, simultaneously.

Traffic into a city can be approached by two main roads; road A and road B. Traffic
load on each road (measured in vehicles per minute) is a Poisson distributed random
variable with mean arrival rates: A = 5 min-¹ and AB = 6 min-¹.
Consider the traffic loads on the two roads to be independent. The blocking of traffic
on each road are characterised by two events:
A: blocking of traffic on road A
B: blocking of traffic on road B
The probability of event A and B are P(A) = 0.10 and P(B)=0.25, respectively.
