2. Red light: Pedro drives the same route to work on Monday through Friday. His route includes one traffic light.

Answer:

So, the probability is P=0.018.

Step-by-step explanation:

We know that Pedro drives the same route to work on Monday through Friday.

We know that there is a 55% chance that the light will be red.

We get that p=55%=0.55.

We conclude that the probability of not being a red light:

q=1-p=1-0.55=0.45.

We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:

$P=q^5\\\\P=0.45^5\\\\P=0.018$

So, the probability is P=0.018.
