Eric has two identical number cubes the faces of each cube are numbered 1-6 eric will roll both of the number of cubes at the same time. What is the probability that both of the numbers showing face up will be multiples of 3?
2/9
1/3THIS ONE
1/6

24 is not correct it's 15
Idk if I can trust UWU
koolaid+man is correct! It's 15.
The Sundae example...
It is a "Combination" as "order does not matter", thus 6 choose 4 (which is not the answer you have decided upon)
The number cubes...
If you consider a tree diagram you need the branch along which both die turn up multiples of 3.
The number of multiples of 3 would result in the numbers 3 or 6 coming up (out of the six possible) so 2/3 = 1/3 but then you need a multiple of 3 followed by another multiple of three so
1/3 x 1/3
= 1/9
6 taken 4 at a time with no order
6!/[4!(2!) ] = 6 *5 / 2 = 15
3,3
3,6
6,3
6,6
is 4 out of 36 = 1/9
