drawn card being a black ten or a king is
​

Answer 1

Answer:

black ten=1/26

a king=1/13

Step-by-step explanation:

there are 2 black ten in the pack

so, probability of black ten is =

2/52

1/26

and there are 4 kings in pack

so, the probability of a king is=

4/52

1/13

Answer 2

Answer:

the no. of ways of drawing one card out of pack of 52 cards is 52C1 i.e. 52.

now, there are two black tens in a pack of cards

10 of spade and 10 of club.

no. of ways of drawing one card out of these two cards is 2.

further there are four kings in a pack of cards. no. of ways of drawing one king is 4.

the two evens are mutually exclusive.

Hence, the probability of a card being black ten or a king = probability of card being ten of black + probability of card being a king

= 2/52 + 4/52

= 6/52

= 3/26
