Answer:
Number of students= 820.64 = 821
Step-by-step explanation:
Giving the following information:
Current attendance= 950 students
Number of periods= 3 years
Decrease rate= 5%
<u>To calculate the number of students in attendance in 3 years, we need to use the following formula:</u>
Number of students= current attendance*(1+decrease rate)^(-n)
Number of students= 950*(1.05^-3)
Number of students= 820.64 = 821
Answers:
a) 0.0625
b) 0.9375
==================================================
Work Shown:
The probability of landing on heads is 1/2 = 0.5 since both sides are equally likely to land on. Getting 4 heads in a row is (1/2)^4 = (0.5)^4 = 0.0625
The event of getting at least one tail is the complement of getting all four heads. This is because you either get all four heads or you get at least one tail. One or the other must happen. We subtract the result we got from 1 to get 1-0.0625 = 0.9375
You can think of it like this
P(getting all four heads) + P(getting at least one tail) = 1
The phrasing "at least one tail" means "one tail or more".
