Final answer:
The correct Python code for correcting the given method to calculate the sum of the squares of the two largest numbers among x, y, and z is provided.
Step-by-step explanation:
To correct the method and obtain the sum of the squares of the two largest numbers among x, y, and z, we can use the max() function. This function returns the maximum value from a sequence of numbers. Therefore, the corrected code for the method would be:
def two_of_three(x, y, z):
return x**2 + y**2 + z**2 - max(x, y, z)**2
This updated code will calculate the sum of the squares of x, y, and z, and then subtract the square of the largest number among them.
