Step-by-step explanation:
I will illustrate this solution with a unique birthday party situation between Jane (the celebrant) and her 10 friends.
In the said party , we will assume that Jane only has 5 chocolates to share among her friends
i. Assuming that the 5 chocolates are of the same type, if she doesn't want to give any friend more than one piece of chocolate, the situation here is said to be WITHOUT REPLACEMENT & UN-ORDERED
n = 10 and k = 5
Total number of possible combinations becomes,
ii. Assuming that the 5 pieces of chocolate are of the same type and she is willing to give a friend more than one piece of chocolate, the situation is said to be WITH REPLACEMENT & UN-ORDERED

iii. Assuming that the 5 pieces of chocolate are of different types and she isn't willing to give any friend more than one piece of chocolate, the situation is said to be WITHOUT REPLACEMENT & ORDERED
n = 10 & k = 5
Total number of possible combinations becomes,
iv. Assuming the the 5 pieces of chocolate are of different types, if she is willing to give a friend more than one piece of chocolate, the situation is said to be WITH REPLACEMENT & ORDERED
n = 10 AND k = 5
Total number of combinations becomes
Sampling with replacement means that one friend can be sampled more than once i.e: A friend receives a piece of chocolate more than once
The order dictates how the sampling is applied.
Answer: x=2π/3 and x=4π/3
Step-by-step explanation:
The equation we have is . All we have to do is get cosine alone to find the 2 values of x.
Now that we have our cosine left, we can use our unit circle to figure out when does cosx=-1/2. Cosine is the x value of the coordinate.
x=2π/3
x=4π/3
