Answer:

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

Hello from MrBillDoesMath!
Answer:
The lines do not intersect
Discussion:
Where do the lines intersect?
5x + 4 = 5x - 3     =>                   subtract 5x from both sides
4         =       -3      =>  NO WAY! The lines do not intersect
Thank you,
MrB

Answer:
answer a
Step-by-step explanation:
 <
 < 
- Let's isolate  on one side of the equation. Ignore the inequality for now. We'll deal with that later. on one side of the equation. Ignore the inequality for now. We'll deal with that later.

- Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating  , but if this confuses you, just do your math and keep the inequality there. , but if this confuses you, just do your math and keep the inequality there.
 <
 < 
- On a number line, this would include every number <em>less than </em> , due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em> , due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em> . But, how do we decide between answers a and c? . But, how do we decide between answers a and c?
- If a line has point at its beginning,  , then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer. , then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer.
