A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago.

The specifications sheet says that the chance of failure is 5% after 5 years and increases to 8% after 10 years. If the gears on the machine are in no way linked to each other, what are the chances that both will fail?

These are independent events so
P(A and B) = P(A) * P(B)

Therefore
P(Both gears fail) = 0.05 * 0.08 = 0.004 or 0.4%

Also we could see that the points are linear.

Hence, the relationship that best describes variable A and variable B is:
