Answer :
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 %
and 8/100 (after 10 years)
Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
Answer:
0.4%.
Step-by-step explanation:
If the gears on the machine are not linked to each other, the probability that both replacement gears will fail is 0.4%.
