Answer 1

@satellite73 help plz

Answer 2

i would think the answer to a) would be 5 and i got this from adding 1,2,3,4 and dividing by 2
For b) i'd try to find how many combinations tou can get 5 with 2 dice and how many non 5's and put the first number over the second.
But i'm just guessing using a little logic.

Answer 3

heyy i found the answer of part b but i still didnt understand logic of part a :\

Answer 4

it's an average the average of all the numbers on 1 dice is 2.5 and you have 2 dice

Answer 5

yea i understood what u did there but why u did that

Answer 6

think of it like this, if you drop the dice 4 times you probaly won't get a 1 a 2 a 3 and a 4, but if you drop them 1000 times tou will probaly get close to 250 1's 250 2's 250 3's and 250 4's

Answer 7

that's what probablilty is since they all have an equal chance to land face down then over time they will land an equal amount of times on each. so since they all have the same chance in the long run we add them all up and devide by how many we have, which in this problem is 4.

Answer 8

man my best guess is 5 is because it came the most times here see the pic

Answer 9

it came out the most times because it has more numbers that will add up to it., 3 only happens when you have a 2+1 or a 1+2 but 5 comes out more because it can be a 1+4 a 4+1 a 2+3 or 3+2 but all you have to know is that the average is the middle option.

Answer 10

have you ever played craps or know what the game is?

Answer 11

it's based off of odds or probability. if you take a 6 sided dice and add up all the numbers and then devide by the number of sides you will get 21/6=3.5
you can't roll a 3.5 but craps is played with 2 dice. that's why the number 7 is so important because it will come up the most times, because more numbers will add up to 7.
