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
![P(L_{1})=P(1)\times P(2)](https://tex.z-dn.net/?f=P%28L_%7B1%7D%29%3DP%281%29%5Ctimes%20P%282%29)
Where
P(1) is the probability of person passes through ![L_{1}](https://tex.z-dn.net/?f=L_%7B1%7D)
P(2) is probability that the radar is operating
![P(L_1)=0.2\times 0.4=0.08](https://tex.z-dn.net/?f=P%28L_1%29%3D0.2%5Ctimes%200.4%3D0.08)
Similarly the probabilities are calculated for other radars in the similar manner as
![P(L_2)=0.1\times 0.3=0.03](https://tex.z-dn.net/?f=P%28L_2%29%3D0.1%5Ctimes%200.3%3D0.03)
![P(L_3)=0.5\times 0.2=0.1](https://tex.z-dn.net/?f=P%28L_3%29%3D0.5%5Ctimes%200.2%3D0.1)
Thus the reuired probability of the reuired event is
![P(E)=P(L_1)+P(L_2)+P(L_3)+P(L_4)\\\\P(E)=0.08+0.03+0.1+0.06=0.27](https://tex.z-dn.net/?f=P%28E%29%3DP%28L_1%29%2BP%28L_2%29%2BP%28L_3%29%2BP%28L_4%29%5C%5C%5C%5CP%28E%29%3D0.08%2B0.03%2B0.1%2B0.06%3D0.27)
