Answer: No, the experiment is not binomial

Step-by-step explanation:

From the formula for a binomial distribution :

nCx * p^k * q^(n - x)

n = number of trials (fixed)

x = number of success on trial

p = probability of success (which is the same for each trial).

q = (1 - p) = probability of failure (same for each trial)

Binomial experiment have binary outcome ; Either Success or Failure

The experiment described above :

Number of trials is satisfied (8 picks)

Binary outcome (matches on ticket or match does not exist).

It takes a while to see through this one. 
I think that's because the triangle is in a weird position.

The arrows on the two across-lines tell us that those lines are parallel.
And THAT tells us that the two triangles are similar ... the whole big triangle,
and the smaller triangle on the bottom.

If two triangles are similar, then what ?

-- Their corresponding angles are equal.  That doesn't help us in this problem.

-- Their corresponding sides are in the same ratio.  That helps us a lot !

The left side of the big triangle = 5 + 8 = 13
The left side of the small triangle          =  8

Now we know that corresponding sides of the two triangles
have the ratio of 13 to 8 .

The right side of the big triangle  =  4 + x
The right side of the small triangle = x

The ratio has to be 13/8 ,  so ===>       (4+x) / x  =  13 / 8 .

That's the tough part.  Now you take it and finish it off from here.
