Getting 2 of diamond as there is only one card of 2 in diamond so chances of it getting are 1C1
Getting 3 of spades same.. 1 card only so chances of getting it are 1C1
Now other 3 cards can be anyother leaving aside these 2 for that you need to pick 3 cards i.e 50C3
Now probability of picking all in together is=1C1* 1C1* 50C3/52C5
