Answer:
Where is the diagram though..
Step-by-step explanation:
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:
First we will subtract 16 acres from total land 349 acres.
349-16=333 acres
Now divide 333 by 3
Answer will be 111 lots of 3 acres.
