Solution

Step 1 Finding the total number of outcomes and the number of favorable outcomes:

The event is the selecting a card from the pack.

There are ten of all four suits(Hearts, Diamonds, Spades, and Clubs) from which king, queen, and jack of clubs are removed.

TotalOutcome=Totalcards-(KingofClub+QueenofClub+JackofClub)TotalOutcome=52-(1+1+1)TotalOutcome=52-3TotalOutcome=49

So, the total number of outcomes is 49.

Out of the total number of outcomes, the number of clubs is 13, but the king, queen, and jack of clubs have been already removed.

Numberofclubs=13-(KingofClub+QueenofClub+JackofClub)Numberofclubs=13-(1+1+1)Numberofclubs=13-3Numberofclubs=10

So, the number of favorable outcomes is 10.

Step 2 Finding the probability of getting a club:

The formula for probability is,

Probability=NumberoffavorableoutcomesTotalnumberofoutcomesP(aclub)=1049

Therefore, the probability of getting a club is 1049.
