Question 1129841
<font color="black" face="times" size="3">
Let's call the two cars: car A, car B


Car A has a 9.3% chance of running the red light (intersection of 5th and main) so it has a 100-9.3 = 90.7% chance it does not run a red light.


Car B has a 11.7% of running the red light (intersection 7th and polk) meaning it has a 100-11.7 = 88.3% chance of not running the red light.


Convert each percentage to decimal form
90.7% ---> 0.907
88.3% ---> 0.883


Now multiply those decimal values:
0.907*0.883 = 0.800881
this multiplication works because the two events are independent


Convert the result to percent form
0.800881 ---> 80.0881%
which rounds to <b><font size=4 color=red>80.1%</font></b>


---------------------------------------------


Answer: <b><font size=4 color=red>80.1%</font></b>
This is the probability that both cars together do not run their respective red lights.
