<h3>
Answer: 13/28</h3>
========================================================
Reason:
The table shows he got 26 heads out of 26+30 = 56 coin flips.
26/56 = (2*13)/(2*28) = 13/28 is the empirical or experimetnal probablity of getting heads.
Side note: 13/28 = 0.4643 = 46.43% approximately which is fairly close to 50%
Solving the equation
we get value of p = -4
Step-by-step explanation:
We need to find the value of p in the equation 
Solving to find value of p:

So, solving the equation
we get value of p = -4
