Question

probability of drawing king of hearts given a hearts drwan

Answer 1

king of hearts is 1 out of 52 cards

but it is asking in a heart cards I.e 13 cards

so ,

probability = no. of favorable outcomes / Total no. of outcomes

probability = 1 / 13

Answer 2

a) I get a red card and a king hearts: P(R or K). There are 26 reds card out of 52 cards, so P(R) = 26/52 = 1/2. There are 4 kings out of 52 cards, so P(K) = 4/52 = 1/13. There is 1 card which is a red card and a king of hearts so $$P(\text{H and K}) = \frac{1}{13}\times \frac12 = \frac{1}{26}$$

But I don't know if this is right.
