Answer:
1.25% widgets from factory A fail.
Step-by-step explanation:
Probability of widgets that fail = 0.05
Probability of failing widget to belong from factory A = 0.25
Probability of failing widget to belong from factory B = 0.35
Probability of failing widget to belong from factory C = 0.40
Probability of factory A widgets failing = Probability of widgets failing * probability they belonged from factory A
Probability of factory A widgets failing = 0.05 * 0.25 = 0.0125
This probability stated as percentage: 1.25%
