प्रश्न
A card is drawn from a deck of 52 cards. Find the probability of getting a king or a heart or a red card.
उत्तर
Total number of cards = 52
Favourable events = 4 kings + 13 hearts + 26 red – 13 – 2
= 28
∴ Required probability = `28/52`
= `7/13`.

One urn contains two black balls (labelled B1 and B2) and one white ball. A second urn contains one black ball and two white balls (labelled W1 and W2). Suppose the following experiment is performed. One of the two urns is chosen at random. Next a ball is randomly chosen from the urn. Then a second ball is chosen at random from the same urn without replacing the first ball. Write the sample space showing all possible outcomes
