A red and a green dice are rolled. 

What's the probability that the sum of the pips on the top face is 5 or showing number greater than 3 ? 

This is usually the best way to do 2 dice questions - you will always see a pattern emerge.

There are 27 possibilities that have a number greater than 3 They are red.

There are 4 that add to 5 they are highlighted in yellow.

There are 2 that are in both groups.  You do not want to add those twice.

So number of possibilities is      27+4 -2 = 29

So the probability that the sum of the pips on the top face is 5 or at least one of the numbers is greater than 3 is    

                   \(\frac{29}{36}\)

Oh! Thanks, Guest! I didn't see it that way!

If what you're saying is correct, then, then your work would be righ. The events' probabilities are 1/6 and 1/9, and multiplying them would result in the probability of both events occurring. 1/6*1/9=1/36,  which means that the probability of the sum of the top faces being 5 AND at least one number greater than 3 being rolled is 1/36.

However, there is a chance that the probability of either one happening was asked, and in that case, CPhill nailed it!

Thanks, CPhill and Melody! This site wouldn't be the same without you!

1.12*3=3.36.

You can just multiply each place value by 3.

Also, you can easily access this site's calculator by clicking on the Home tab at the top of the page.

Thanks for all the help guys!

Just out of curiousity Mr. Guest. What financial software do you use?

Supply

1 x 3=3 0.12 x 3 = 0.36 3+0.36=3.36(84/25)

Ans thanks for giving our guests this great advice too.   

its 12 - 3 its not that hard

12 /  2/3      =    12 x  3/2 =  36/2 = 18 servings

I'm good you?

His name is austink

Thanks, Anonymous4338......!!!!

We can use something called Heron's Formula to find this area

The area is given by :

A  = sqrt [ s (s - a) (s - b) ( s - c) ]       where a,b,c are the lengths of the triangle's sides and s is the  "semi-perimeter"   calculated as

s = [a + b + c] / 2   = [100 + 250 + 275]/2   = 312.5

So  the area is

sqrt [ 312.5 (312.5 - 100) (312.5 - 250) (312.5 - 275) ]   ≈  12,475.56 square meters

There are many solutions to this. For instance :

If   x = 1 , y = 2 and z = 0

x + y + z = 3

And

xy + xz + yz - xyz =

2 +  0   +  0  -  0   =   2  ≤  9/4

Switching x and y values and letting z remain 0  would work, as well

if all x =1 z=1 y=1 xy+xz+yz=3 so 3-xyz=2 9/4=2.25. so 2.25>2!

Let  P(F)  = the probability that the sum of the pips on the top face = 5

This is = 4/36   =  1/9

Let P(G)  = the probability that a number greater than a three is rolled.  This is the same probability that  1 - [a number 3 or less is rolled]  = 1- [ probability that a 2 is rolled + probability that a 3 is rolled] = 1 - [ 1/36 + 2/36]  = 36/36 - [ 3/36]  =  33/36  = 11/12

So

The probability that F or G occurs  =

P( F or G)   =

P(F) + P(G)  - P(F and G) =

(1/9) +  (33/36)  -  [ (1/9)(11/12)]  =

(4/36) + (33/36) - [ 11/108]  =

(12/108) + (99/108) - (11/108)  =

100/108 =

25/27

Hello, 

Actually I think you did not get the question 

He's asking about both event at the same time ? So youc an't answer 1/6 and 1/9 

You ahve to compounded them. 

There is 4 chance out of 36 for the 5 

and then you have to had the solution for 3 

There is 1 chance out of 36 so there is 5 chance ot ouf 36 if I do not make any mistakes ? 

Like said in my other post, subtracting a a negative is the same as adding the positive value of that number.

1-(-1)=1+1=2

THANK YOU!!

2 because 1-(-1) = 1+(+1) because you add the opposites 

-59999200000

When subtracting a negative, you can just add the absolute value of the negative you are subtracting from the other. Two negatives make a positive, and since you are subtracting (negative) a negative (two negatives), you are simply adding.

 1-(-1) turns into...

1+1

I think you can figure the rest out! 

2

1-(-1)=1+1=2

Subtracting a negative is basicly like adding the same numbers

Well you could specify.
