When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
The price in dollars per gallon is 4.02 dollars per gallons.
<h3>How to find the price of gasoline in dollars per gallon?</h3>
Gasoline costs 1.05 euro per litre in France.
The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.
Then, equate it the quantity of litres to gallons.
Hence,
1 euro = 1.01 dollars
1.05 euro = ?
cross multiply
price = 1.05 × 1.01
price = 1.0605 dollars
1 litres = 0.264172 gallons
Therefore,
cost = 1.0605 / 0.264172
cost = 4.01552442257 dollars per gallons
cost = 4.02 dollars per gallons
Therefore, the price in dollars per gallon is 4.02 dollars per gallons.

Step-by-step explanation:
Total number of balls in the bag is
4+6+3 =13
13 - 6 will be used to calculate how many of the balls are not white and only 7 are NOT white therefore, the probability will be
7/13 7 non white balls/13 balls in total
