Answer:
66.67% probability that all selected components function properly
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the components are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Desired outcomes:
2 components which function properly, from a set of 5. So

Total outcomes:
2 components, from a set of 6. So

Probability:

66.67% probability that all selected components function properly
No because if that happened they wouldn’t be able to do it again so yeah
Six hundred fifty five thousand five hundred seventy five
You're going to have to take a better quality picture. I don't think anyone can reliably read any of that
Answer:

s = d/t
d = st
d = 16 miles/hr × 0.25 hr
d = 4 miles
