Answer:
The water dispenser's capacity in liters is 20liters
Explanation:
Given:
A water dispenser capacity = 20,000milliliters
To find
the capacity of the water dispenser in liters
To determine the capacity in liters, we will convert the capacity in ml to liters using the conversion:
1000ml = 1 liter
let the capacity of the water dispenser in Liters = y
The water dispenser's capacity in liters is 20liters
"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)
Theoretical Probability of rolling a 1: 1/8
Experimental Probability of using coupons: 4/48 = 1/12
So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).
Answer:
yes
