**Chapter 14 Probability Case study Questions Class 10 Maths**

**I. Garima has two children, Tapan and Maya. Every Sunday is a game night in the family. Tonight Garima has planned for a game with three cubes, one purple and two yellow. She placed the three cubes in a bag and called for her children.****Garima: Do you want to play a game of probability?****Maya: What is probability?****Garima: Let me ask you something before I answer you. Can you predict what is in this bag?****Tapan: I cannot guess that!****Maya: I am 100% sure it is a toy!****Garima: I am glad you think that Maya. Just now you used the concept of probability.****Whether an event can happen or not, can’t be predicted with total certainty. But we can always predict how likely or unlikely it is for an event to happen.****And for predicting that, we use a concept called probability.****Probability (an event to happen) = Number of ways event can happen/ Total number of ways all events can happen****Placing the bag of cubes in the centre, Garima explained the rules of the game to the children.****Garima: Without looking, the first player will pick out a cube from the bag and then the second player will also pick out one cube without looking. If the two cubes picked out were the same colour, then the first person will win the game. If the boxes picked out are of two differently coloured cubes, then the second player will be the winner.**
