I'm going to take a guess regarding what you meant to type in:
<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6
3(x+3) 6x+5
becomes E(x) = ----------- * ------------
x-9 5x+6
This cannot be reduced.
Try again to share this problem. Thank you.

Answer:
Therefore the probability that a pen from the first box and a crayon from the second box are selected is 
Step-by-step explanation:
Probability:
The ratio of the number of favorable outcomes to the number all possible outcomes of the event.

Given that,
Three plain pencils and 5 pens are contained by the first box.
Total number of pens and pencils is =(3+5)=8
The probability that a pen is selected from the first box is
=P(A)


A second box contains three colored pencils and three crayons.
Total number of pencils and crayons is =(3+3)=6
The probability that a crayon is selected from the second box is
=P(B)


Since both events are mutually independent.
The required probability is multiple of the events
Therefore the required probability is
