Answer:
The answer is 2881
Step-by-step explanation:
Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)
Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
I’m thinking 9 if you add both equations together then you’ll have 2x+x and y-y=5+4
3x=9
If you wanted to go further then it would be x=3 but for this I’d say the answer is 9
