Simple....
you have:
to convert them into improper fractions:
1.) Take whole number*denominator
(5*5=25)
2.) Take what you got...and add the numerator
(25+2=27)
3.) Use the original denominator
Do the same to the other one...
2*13=26
26+10=36
Now..add...
But..you need a common denominator!
Now you can add!
When simplified....
Thus, your answer.

Answer:
Step-by-step explanation:
Number of red balls = 4
Number of green balls = 6
Total number of balls = 6+4 =10
Probability of drawing a green marble is given as
⇒
⇒
The ball is replaced after drawing.
Probability of drawing a green ball a second time will be:
⇒
⇒
Thus, probability of drawing 2 green balls with replacement can be given as:
⇒ (Probability of drawing a green marble) (Probability of drawing a green ball a second time)
⇒
⇒
Simplifying fraction by dividing numerator and denominator by their GCF.
