5x6=25x5=125 (125) I think it’s correct
So, put your "x's" together first and then your intercepts. That should answer your question :)
Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:

The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:

I think the best answer would be things that can be naturally replaced in a short period of time
The answer is 960 ÷ 4 = 240. I hope this helps
