Searching for the 'p' value in a coin toss simulation

Newbie to coding, attempting to find the 'p' value in a coin toss simulation. Currently getting the attribute error:

'int' object has no attribute 'sum'.

How could it be? please Help.'''

import numpy as np
import random
attempts = 0
t = 0

for I in range (10000):
      attempts = random.randint(2, 30)
      if (attempts.sum >= 22 ):
      t += 1

p = t / 10000 
print(p)
