What’s the square root of 8
kirill [66]

It's none of those, but the last is quite close to the exact value. You can find approximate square roots by trial and error: for sqrt(8), 2 is too small and 3 is too big, so try 2.5, 2.6, 2.7, 2.8, and 2.9. You'll find the answer is between 2.8 and 2.9.

tigry1 [53]

Answer:

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

Step-by-step explanation:

Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k

f_X(k)=P(X=k)

In this case we have the event  

“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.

Then we have 2 possible events, either the computer is right or not.

Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function

f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}

This gives the probability that k computers are wrong at the same time.
