A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fai

azamat

Answer:

Probability (Both fail) = 0.001369

Probability (None fails) =0.927369

Probability (at least one fails) = 0.072631

Step-by-step explanation:

given data

Probability (fail) P = 0.037

two alternators is independent

solution

we get here first probability that both will fail will be

Probability (Both fail) = 0.045² ................1

Probability (Both fail) = 0.001369

and

now we get probability that neither will fail

Probability (None fails) = (1-0.037)² ...............2

Probability (None fails) =0.927369

and

now we get probability that at least one fails

Probability (at least one fails) = 1 - Probability (non fails) .................3

Probability (at least one fails) = 1 - 0.927369

Probability (at least one fails) = 0.072631

A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes

Sergio039 [100]

Hello there.

Question: <span>A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes to school. why might the sample be biased?

Answer: It might be biased as the survey was only taken of students who ride their bikes to school. It is most likely that they would agree to it. To make it fair they survey should have been taken of a variety of different students.

Hope This Helps You!
Good Luck Studying ^-^</span>

In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. One dark morning you pull two socks from t

pishuonlain [190]

Answer:

D) 0.500

Step-by-step explanation:

Blue Socks = 6

Grey socks = 10

Probabilities to find :

Since there are a total of 16 socks, the probability of both socks being blue is

Probability(blue) = $(\frac{6}{16} ) \frac{5}{15} =\frac{30}{240} =\frac{1}{8}$

The probability of both being grey is

Probability(grey) = $(\frac{10}{16} ) \frac{9}{15} =\frac{90}{240} =\frac{3}{8}$

(Note: After 1 sock is picked , next sock drawn would have a different probability as 1 sock is already picked so it would be 1 minus the total socks available of that color)

The probability two socks match:

Probability(blue) + Probability(grey) = $\frac{1}{8}$ + $\frac{3}{8}$ = $\frac{4}{8}$ = $\frac{1}{2}$ = 0.500
