Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a seven or king. (b) compute the probability of randomly selecting a seven or king or jack. (c) compute the probability of randomly selecting a queen or spade.

Total no. of cards = 52

No. of spade cards =13

Spade cards={2,3,4,5,6,7,8,9,10,K,Q,J,A}

No. of heart cards= 13

Heart cards={2,3,4,5,6,7,8,9,10,K,Q,J,A}

No. of diamond cards=13

Diamond cards cards={2,3,4,5,6,7,8,9,10,K,Q,J,A}

No. of club cards = 13

Club cards={2,3,4,5,6,7,8,9,10,K,Q,J,A}

a) Compute the probability of randomly selecting a seven or king. ​

Total no. of kings = 4

So, probability of getting a king =

                                                    =  

                                                    =  

Total no. of cards of 7 = 4

So, probability of getting a 7 =

                                                    =  

                                                    =  

So, the probability of randomly selecting a seven or king =    

                                                                                              =    

b)Compute the probability of randomly selecting a seven or king or jack.

Total no. of kings = 4

So, probability of getting a king =

                                                    =  

                                                    =  

Total no. of cards of 7 = 4

So, probability of getting a 7 =

                                                    =  

                                                    =  

Total no. of jack = 4

So, probability of getting a jack =

                                                    =  

                                                    =  

So, the probability of randomly selecting a seven or king or jack:

=  

=  

c)Compute the probability of randomly selecting a queen or spade.

No. of queens = 4

So, probability of getting a queen =

                                                    =  

                                                    =  

No. of spade cards = 13

So, probability of getting a spade =

                                                    =  

                                                    =  

So, the probability of randomly selecting a queen or spade =    

                                                                                                   =    

the answer is: -22 also a
