Amardeep,
Thank you so much for your very helpful post. I was in the middle of compiling a list of probablity questions myself when I realized that you had already done so.
Thanks again!

I have a question regarding the #37 question and the answer given.
37. How many 5 digit numbers can be created if the following terms apply: the leftmost digit is even, the second is odd, the third is a non even prime and the fourth and fifth are two random digits not used before in the number?
a) 2520 b) 3150 c) 3360 d) 6000 e) 7500
37. The best answer is A. The first digit has 4 options (2,4,6,8 and not 0), the second has 5 options (1,3,5,7,9) the third has 3 options (3,5,7 and not 2), the fourth has 7 options (103 used before) and the fifth has 6 options (104 used before). The total is 4*5*3*7*6=2520.
Now, it is not mentioned that a number cannot be repeated in for the 3rd digit. Say in the 2nd digit the number is 3 and so it is for the 3rd digit. The structure can be 233, now for the 4th digit the option is 8 not 7.
Surely then the answer given is not right. But I don't know how to proceed further. Can someone please help? Or am I wrong about the porcess?
