Now we can get the parameters of success by adding up the gamma of skill1, 2, and 3. We can also get the parameters of failure in the same way -- by adding up the rho of skill1, 2 and 3.



There's one more component to PFA -- the beta. For now, let's say that the beta in column 'beta-param' is 1. Based on what we learned from the lecture, what would be the formula for column 'm'?"




Select one:
A) df['m'] = df['success-param'] - df['fail-param'] - df['beta-param']
B) df['m'] = df['success-param'] - df['fail-param'] + df['beta-param']
C) df['m'] = df['success-param'] + df['fail-param'] - df['beta-param']
D) df['m'] = df['success-param'] + df['fail-param'] + df['beta-param']
E) df['m'] = df['success-param'] * df['fail-param'] * df['beta-param']
