To calculate final cost you need to add tax and tip. Because you tip on the food bill without tax, you just add these two.
72 * 0.2 = 14.4 -> tip
72 * 0.06 = 4.32 -> tax
72 + 14.4 + 4.32 = 90.72
So the total cost was $90.72
You can find that faster:
72 * 1.26 = 90.72
Answer:
0.008
Step-by-step explanation:
The probability of having chosen the unique dice three times in a row would be the multiplication of the probability of each event.
The event is always repeated. Take the single dice of 5 dice in total. Therefore the probability is 1/5.
Then the final probability would be:
<em>(1/5) * (1/5) * (1/5)</em>, and that is equal to 0.008.
