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
Answer:
$5.00
Step-by-step explanation:
10 × 50/100
Discount = 10 x 0.5
You save = $5.00
total = 3000*(1-0.011)^10
1-0.011 = 0.989
total = 3000*(0.989)^10
0.989^10 = 0.895288314
3000* 0.895288314 = 2685.86
rounded to nearest whole number = 2686
there will be 2686 people

161 ft squared
U times any number by 3 and see witch ones the closest
27x3=81 that's what I think and that's the closest
