When one ball is drawn from a bag containing 12 balls each of which is written each of natural numbers from 1 to 12 and put back in and then draw one ball again, find the number of cases in which the number written on the first ball is less than 3, and the number written on the next ball is 10 or greater, 
1 12 1 [OP_LIST_ARANGE] 3 [OP_LIST_LESS] [OP_LIST_LEN] [OP_LIST_POP] 10 [OP_LIST_MORE_EQUAL] [OP_LIST_LEN] [OP_MUL]
var_a = 1
var_b = 12
var_c = 1
list_a = [i for i in range(var_a, var_b + 1, var_c)]
var_d = 3
list_b = []
for i in list_a:
    if i < var_d:
        list_b.append(i)
var_e = len(list_b)
var_f = 10
list_c = []
for i in list_a:
    if i >= var_f:
        list_c.append(i)
var_g = len(list_c)
var_h = var_e * var_g
print(int(var_h))
