Hello I hope I can help you with this!!
EXPLANATION:
first we work out what all the marbles equal which is 9/9=63
Then we work out what 1/9 of the marbles are! Which is 1/9= 7 marbles!!
Then we work out what 5/9 of them are! Which is 5/9= 35 marbles
Then now we work out 4/9 which is our RED marbles! We do 4 times 7 which equals 28 red marbles!!
if you want to check to add the two numbers and they equal 63!
ANSWER= 28 red marbles
Answer:
There are (63) combinations. The notation means "six choose three". Out of six items (flavors) choose three.
(nk)=n!k!(n−k)!.
(63)=6!3!3!.
Think of it this way. There are 6 ways to choose a flavor. Once you choose, there are 5 ways to choose the next. After that, there are 4 flavors left. which is 6!/3!=6⋅5⋅4⋅3⋅2⋅13⋅2⋅1=6⋅5⋅4=120.
But, you could have chosen {chocolate,vanilla,strawberry} and you get the same combination as {vanilla, strawberry, chocolate} so we have to divide by 3!=3⋅2⋅1=6 to account for the order of choosing.
So the number of combinations of flavors is (63)=1206=20.
