Answer:
No
Step-by-step explanation:
The definition of a prime number is a number that only has factors of 1 and itself. So there are only 2 factors.
4 has 3 factors: 1, 2, and 4. It has factors of 1 and itself (4), but also has an extra factor (2), so 4 is not a prime number
Answer:
She makes $4.66
Step-by-step explanation:
In this problem we are required to calculate the profit she makes from each bracelet
Given data
Selling price for a bracelet =$9
Cost price for a bracelet = $4.35
Profit= selling price- cost price
Profit = 9-4.35= $4.66
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that

Now we replace P(Y) * P(X) for P(Y∩X)

Cancel out P(X)
So 
Like that

Now we replace P(X) * P(Y) for P(X∩Y)

Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
