Answer:
The correct option is B) 0.8x
Step-by-step explanation:
Consider the provided information.
Nancy is buying a new pair of boots. The store is having a sale and all boots are 20% off.
Let the original price is represented by x.
After getting 20% off the amount need to pay is:
Sale price = x-20% of x
Hence, the sales price of the boots is 0.8x.
Thus, the correct option is B) 0.8x
Answer:
a. 0.25
b. 0.50
c. 0.75
Step-by-step explanation:
P(E1) = 0.25
P(E2) = 0.25
P(Es) = 0.25
P(E) = 0.25
a. Since there are 4 outcomes with the same probability of occurring, the probability of E occurring is:
b. The probability of any two outcomes occurring is twice the probability of a single outcome occurring
c. The probability of any three outcomes occurring can be written as 100% minus the probability of the remaining outcome occurring
