Answer:

Step-by-step explanation:
Let
represent students playing basketball,
represent students playing baseball.
Then,
, 
Let
be the total number of students. So,
.
Now,


3 students play neither of the sport. So, students playing either of the two sports is given as:

∴ 
From the probability addition theorem,

Where,
is the probability that a student chosen randomly from the class plays both basketball and baseball.
Plug in all the values and solve for
. This gives,

Therefore, the probability that a student chosen randomly from the class plays both basketball and baseball is 
I believe the first answer is correct
The angles are congruent meaning that you can set them equal to each other:
26 = 5x + 11
Now you can solve for x
26 - 11 = 5x + (11 - 11)
15 = 5x
15/5 = 5x/5
x = 3
