Answer:
1/6
Step-by-step explanation:
I think this is tricky.
when you randomly choose the 1st two times, it doesn't matter as long as Na was not chosen, otherwise the probability would become ZERO for the 3rd one be Na.
So, after 1st two is removed, there are only 4 left in the pool, so picking Na at the 3rd draw is 1/4 probability.
But, come to think of it, when 1st draw, you have to draw the other 5 out of 6, 2nd draw the 4 out of 5, then 3rd is 1 Na out of the 4.
So, 5/6 x 4/5 x 1/4 = 1/6
Answer:
4^(5+2) + 7 - (4^(-3+2) +7)
--------------------------------------
5 +3
Step-by-step explanation:
The average rate of change is given by
h(5) - h(-3)
---------------
5 - -3
h(5) - h(-3)
---------------
5 +3
h(5) = 4^(5+2) + 7
h(-3) = 4^(-3+2) +7
4^(5+2) + 7 - (4^(-3+2) +7)

5 +3
