The answer for your problem is shown on the picture.
Should be 7.5% I have to add more words to this sentence to post it
The sample space will be: {1, 2, 3, 4, 5, 6}
Event A is: {Rolling 1,2 or 3}
Complement of event A will contain all those outcomes in the sample space which are not a part of event A.
So, complement of event A will be: {Rolling a 4,5 or 6}
Thus option A gives the correct answer
Answer:
The margin of error for a sample size of 250 is 6
Step-by-step explanation:
The margin of error is given as
1/square root of the sample size
Thus, margin of error for a sapless size of 250 is
1/√250
= 1/15. 811
= 6
Hi there
Annual yield=annual interest÷bond cost
Annual interest=1,000×0.06=60
Bond cost=1,000×0.805=805
So
Annual yield=60÷805=0.0745×100
=7.45%
Good luck!
