Using it's concept, it is found that there is a 
probability that the first card is a club and the second one is black.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- In a deck, there are 52 cards, of which 13 are clubs, hence
.
- Then, of the remaining 51 cards, 26 are black, hence
.
Then:
probability that the first card is a club and the second one is black.

The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint
