10% chance of burning out
100-10= 90% chance of not burning out
90% = 0.9
3 lightbulbs
0.9^3 = 0.729 = 72.9%
The probability that all 3 lightbulbs stay lit by the end of the month is 72.9%

Mathematics

(1, 5)

Step-by-step explanation:

The line of reflection is y = 1, which is a horizontal line with a y-intercept of 1. Each point must be the same distance away from this line, but on the other side of it. For example, X is 4 units away from y = 1, so X' must also be 4 units away, but on the other side. X' ends up at (1, 5).
