Hi there!

First, you select a random card. You have a 1/20 chance of selecting any card. Then, without replacing the first card, you draw a second card. You have a 1/19 chance of selecting any card. In order to find the chance of both, you'll need to multiply the fractions together, giving you the 1/380 chance.

ANSWER:
Option 4 - 1/380


Hope this helps!! :)
