If you roll two four-sided dice (numbered 1, 2, 3, and 4), what is the probability that the sum of the dice is 3?
Elan Coil [88]

Answer:

The probability that the sum of the dice is 3, is 3/16.

Step-by-step explanation:

It is given that two four-sided dice are rolled.

Total number of sides of each dice = 4

Possible values for each dice = 1,2,3,4

If two four-sided dice are rolled, then the total possible outcomes are

A=\{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),\\(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)\}

Total number of possible outcomes = 16

The sum of the dice is 3.

\text{Favorable outcomes}=\{(1,1),(1,2),(2,1)\}

Total number of favorable outcomes = 3

The probability that the sum of the dice is 3.

Probabilty=\frac{3}{16}

Therefore the probability that the sum of the dice is 3, is 3/16.

URGENT HELP PLEASE!!!! 20 points!
LuckyWell [14K]
To solve this, we need the formula for the volume of a sphere. The formula is expressed as the 4/3 of the product of the cube of the radius and pi.Volume = 4/3 (π x r^3)
Substituting the given values, we have:
Volume = 4/3 (3.14 x 21^3)Volume = 38772.720 cm^3
Thus, the approximate volume of the container is 38772.720 cm^3.

Choice 4 is f(x)=-4x+4
alekssr [168]
The answer would be the 3rd one, we find this by gettign our facts, first find our y-intercept, where does the line pass through the y line, it passes through the positive 4, now lets find the slope, the slpe is the rise over run, the graph rises 4 and runs 1 to the right, so your slope will be 4 now how do you know if its a positive or a negative, well if the graph rises to the right it is a positive and if it rises to the left is a negative... This graph rises to the right so  our slope is a positive... SO our equations should look like f(x)=4x+4 and our 3rd option has exactly this answer, so your answer would be the 3rd one

Hope this helps
