Answer:
69.23% probability that a person is not qualified if he or she was not approved by the manager.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes:
In this problem, we have these following probabilities:
80% probability that a person is qualified
20% probability that a person is not qualified.
90% probability that a qualified person is approved.
10% probability that a qualified person is not approved.
10% probability that an unqualified person is approved.
90% probability that an unqualified person is not approved.
Find the probability that a person is not qualified if he or she was not approved by the manager.
Desired outcomes
Unqualified and not approved.
20% are not qualified. Of those, 90% were not approved. So
Total outcomes:
Qualified and not approved or unqualified and not approved.
80% are qualified. Of those, 10% were not approved
20% are not qualified. Of those, 90% were not approved. So
Probability
69.23% probability that a person is not qualified if he or she was not approved by the manager.
Answer:
The mileages for which company A charge less than company B when , y 50 .
Step-by-step explanation:
Given as :
The two truck companies have following prices
Company A
The initial fee = i = $110
And unlimited mileage
Company B
The initial fee = I = $65
Additional charge = $0.90 per mile driven
Let it driven x mile
Let The mileages for which company A charge less than company B = y
<u>Now, According to question</u>
Charges of company A = charges of company B
i.e i = I + 0.90 × x
Or, $110 = $65 + 0.90 × x
Or, $110 - $65 = 0.90 × x
Or, $45 = 0.90 × x
∴ x =
i.e x = 50
i.e Company B driven x = 50 miles
So, The mileages for which company A charge less than company B = y
And y x
i.e y 50
Hence, The mileages for which company A charge less than company B when , y 50 . Answer
