What is the probability of rolling a sum of 3 on a standard pair of six-sided dice?
salantis [7]

To solve this problem, let us recall that the formula for probability is:

Probability = total number of successful events / total events

 

Where in this case, an event is considered to be successful if the sum is 3 on the pair of six sided dice.

 

First, let us calculate for the total number of events. There are 6 numbers per dice, therefore the total number of combinations is:

total events = 6 * 6 = 36

 

Next, we calculate for the total number of combinations that result in a sum of 3. We can identify that there are only two cases that result in sum of 3. That is:

1st case: first dice rolls 1, second dice rolls 2

2nd case: first dice rolls 2, second dice rolls 1

 

Hence, total number of successful events = 2. Therefore the probability is:

Probability = 2 / 36 = 1 / 18 = 0.0556 = 5.56%

A car travels 32 miles for each gallon of gas.How many gallons of gas does it need to travel 192 miles
gladu [14]

Hi there! :)

<u>Answer:</u>

The car needs <u>6 gallons</u> of gas to travel 192 miles.


Step-by-step explanation:

In order to answer your question, you'll need to use the cross product method:

32 miles  → 1 gallon

192 miles → X gallons

<u>(1 × 192)</u> ÷ 32 = X gallons

<u>192 ÷ 32</u> = X gallons

<u>6</u> = X gallons


There you go! I really hope this helped, if there's anything just let me know! :)
