4 1/4
Step-by-step explanation:
you have to find a equal denominator then simplify
Using the probability concept, we have that:
a) It would not be unusual to observe one component fail, since the probability that one component fails is greater than 0.05.
b) It would be unusual to observe two components fail, since the probability that two components fail is less than 0.05.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. If a probability is less than 0.05, the event is considered unusual.
In this problem, the probabilities are given as follows:
- 0.21 probability that one component fails, hence not unusual.
- (0.21)² = 0.0441 probability that two components fail, hence unusual.
