Answer:
The probability that the customer must open 3 or more bottles before finding a prize is 0.64
Step-by-step explanation:
In order for a customer to have to open at least 3 bottles before winning a prize, then the first two bottles shouldnt have a price. The probability that a bottle doesnt have a price is 1-0.2 = 0.8. Since the bottles are independent from each other, then the probability that 2 bottles dont have a prize is 0.8² = 0.64. Therefore, the probability that the customer must open 3 or more bottles before finding a prize is 0.64

m = 4
Step-by-step explanation:
Given
- 8 + 6m = 
(4m + 16) ← distribute parenthesis
- 8 + 6m = 2m + 8 ( subtract 2m from both sides )
- 8 + 4m = 8 ( add 8 to both sides )
4m = 16 ( divide both sides by 4 )
m = 4
