Question

One card is drawn from a pack of 52 cards, each of the 52 cards being equally likely to be drawn. Find the probability that the card drawn is: an ace(ii) red  (iii) either red or king (iv) red and a king.

Answer 1

1)P(diamond)=`13*1/52=1/4`
2)P(not ace)=`12*4*1/52=12/13`
3)P(black)=`26/52=1/2`
4)P(not diamond)=`13*1/52+13*1/52+13*1/52=3/4`
P(not black)=`26*1/52=1/2`.
