Answer:
y = 6
Step-by-step explanation:
24/12 = 2
2*3 = 6
We are asked to determine the probability of having at least one digit of zero in a winning lottery number that is composed of four digits from the set of numbers from 0 to 9. To determine the probability to be known, we can approach this problem by computing for the probability by counting theory for each digit.
Digit 1: there are 10 choices, so the probability is 1/10
Digit 2: there are only9 choices, probability of 1/9
Digit 3: there are also 9 choices, probability of 1/9
Digit 4: 9 digits as 0 is not a included
*(numbers beginning with zero do not count zero as part of the number)
Hence the probability is (1/10)*(1/9)*(1/9)*(1/9) = <span>0.000137</span>
Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70
I hope that this made sense to you.
number 4 is x = 9 and number 5 is x = 10
Given:
1.5 gallons = x quarts
1 gallon is equal to 4 quarts. 1 gal = 4 quarts
1.5 gallons * 4 quarts/gallon = 6 quarts.
There are 6 quarts in 1.5 gallons.
