Python how to structure multiple conditions in an if statement

A student sitting 3 exams will pass if:

• They pass all subjects at 40 points and above, or
• They pass at least two subjects at 40 points or above, and the overall average is strictly greater than 50 points.

Write a function that takes three arguments of the three marks (integers), determines whether a student has passed or not based on the exam scores, and prints "This student has passed." or "This student has not passed."

My attempt at the function is below:

def student_pass(score1, score2, score3):
    
    if (score1 >= 40) and (score2 >= 40) and (score3 >= 40):
        print ("This student has passed.")

    elif ((score1 >= 40 and score2 >= 40) or (score1 >= 40 and score3 >= 40) or (score2 >= 40 and score3 >= 40)) and ((score1+score2+score3)/3 >= 50):
            print ("This student has passed.")

    else:
        print ("This student has not passed.")

However, when I try to produce a "This student has not passed." statement with the inputs student_pass(70,50,30) I still get a "This student has passed." statement.

What could be the problem here?
