Key Topics to Revise

1

1. Basic Idea of Probability

  • A fair coin is symmetrical, so there is no reason for it to come down more often on one side than the other.
  • A random toss means the coin falls freely without bias or interference.
  • For a fair coin, head and tail are equally likely outcomes.
2

2. Important Definitions and General Rules

  • An event having only one outcome of the experiment is called an elementary event.
  • The sum of the probabilities of all elementary events of an experiment is 1.
  • For any event E, the probability of not E is 1 - P(E).
3

3. Standard Examples from Coins, Dice, Balls, and Cards

  • For one coin toss, the outcomes are head and tail, so P(head) = 1/2 and P(tail) = 1/2.
  • For a bag with a red, blue, and yellow ball, Kritika has probability 1/3 of drawing any one specific colour.
  • For a die, getting a number greater than 4 has 2 favourable outcomes: 5 and 6, so probability is 2/6 = 1/3.

4. Complementary Events and Direct Applications

  • If the probability of one event is given, the probability of its complement can be found quickly.
  • If Sangeeta's probability of winning is 0.62, then Reshma's probability of winning is 0.38.
  • For two friends, Savita and Hamida, the probability that their birthdays are different is 364/365.
