Let
be the event "the car stops at the signal.
In the attached figure you can see a tree describing all possible scenarios.
For the first question the red path describes stopping at the first light but not stopping at the second. We can determine the probability of this path happening by multiplying the probabilities on the branches of the tree, thus

For the second one the blue path describes the situation

For the las situation the sum of the two green path will give us the answer

Answer:
Step-by-step explanation:
Since RQT=155
4x-20+3x+14=155
7x-6=155
7x=161
x=23
Part(A):
To solve the system of Linear equations using Substitution:

Consider the first equation, x+y=7 implies x=7-y
