A card is drawn a from a well shuffled pack of 52 cards. Find the probability that card drawn is:
(i) black
(ii) black jack
(iii) black or a king

Answer

N/a

Explanation

Here `n(S)=52`
(i) Let `E_(1)=` event drawing a black card
`implies n(E_(1))=26`
`:. P(E_(1))=(n(E_(1)))/(n(S))=26/52=1/2`
(i) Let `E_(2)=` event of drawing a black jack.
`implies n(E_(2))=2`
`:.P(E_(2))=(n(E_(2)))/(n(S))`
`=2/52=1/26`
(iii) Let `E_(3)=` event of drawing a black card or king
`implies n(E_(3))=26+2=28`
`:. P(E_(3))=(n(E_(3)))/(n(S))=25/52=7/13`
