Answer:
The probability that the person gets a speeding ticket is 0.27
Step-by-step explanation:
The probability that the person receives a speeding ticket is the probability that the person passes through any of the speed limits and the radar is operating at that time.
Let
is the probability that the person passes through radar
and it is operating at that time is

Where
P(1) is the probability of person passes through 
P(2) is probability that the radar is operating

Similarly the probabilities are calculated for other radars in the similar manner as


Thus the reuired probability of the reuired event is

Answer:
80
Step-by-step explanation:
30 = 100
24 = 80
6 x 5 = 30
6 x 4 = 24
5 = 20 because 5 x 8 = 80.
The radius of the base of the container:
20/(2*3.14)=3.18cm
Area of the base:
3.14*3.18*3.18=31.8cm square
The toll of the container :
5453/31.8
=171.5cm
SA=4pir^2
r=20m
SA=4pi20^2
SA=4pi400
SA=1600pi m^2
