The sample space will be: {1, 2, 3, 4, 5, 6}
Event A is: {Rolling 1,2 or 3}
Complement of event A will contain all those outcomes in the sample space which are not a part of event A.
So, complement of event A will be: {Rolling a 4,5 or 6}
Thus option A gives the correct answer
Henry has to wrap five presents for a birthday party and has a length of ribbon to make bows for the presents. He cuts the ribbon into eight equal lengths and uses five of the pieces. With the remaining length of ribbon he is able to make six bracelets to give away at the party
9 decimeters. deci = 0.1
9 *0.1 meters.
0.9 meters
9 decimeters = 0.9 meters.
Substitute
, so that

Then the resulting ODE in
is separable, with

On the left, we can split into partial fractions:

Integrating both sides gives




Now solve for
:


Hmmm...
We have to divide 12 by 8, since we need to see how 8 students will share 12 slices.
12/8=1 and 1/2
So, each student can have a slice and a half, but since we aren't allowed to cut the slices...
We can let each student have one slice, with 4 left over, so...
Every student can have one slice, and then half can have a second slice :)!
I'm not sure if that is what was meant by the question, but that was all I could think of.
I hope I helped! :)
