x^4 / 3

Step-by-step explanation:

This one is kind of hard to explain so follow along and if you have any further questions for clarification, don't be afraid to call me out and ask.

So this is a division question. You divide x by x and y by y.

So at the top you have 4 and right below you have 12 right?

You can divide those!

4/12 is 0.333333333 which in fraction form is 1/3

So now you have x^6 y^6 / 3 x^2 y^6

Next we can divide x^6/x^2

You have to subtract exponents when they are divided because of the quotient rule.

For example, a^10 / a^6 you'd do a^10-6 = a^4

So x^6/x^2 = x^6-2 = x^4

So now your left with X^4 y^6 / 3 y^6

Lets do y.

y is just like x

y^6/y^6 = y^6-6 = y^0

When the exponent = 0 the number is always one even if its a variable

For example: a^10/a^10 = a^0 = 1

So now your left with x^4/3

and that's your final answer!

If you have any further questions, don't be afraid to reach out and I hope that helps!

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
