    Study Notes

    • A ₹10 coin that is being tossed has two possibilities: heads or tails.
    • When the coin is tossed, there are two events: coin landing on heads or coin landing on tails.
    • The probability of getting heads is equal to the probability of getting tails.
    • The probability of getting heads or tails is calculated by dividing the number of successful outcomes by the total number of outcomes.
    • In the case of the coin flip, the successful outcomes are the number of heads or tails obtained, and the total number of outcomes is the total number of flips.
    • If a coin is flipped multiple times, the probability of getting a specific outcome in each flip is the same.
    • In a single flip, the probability of getting heads is 1/2 or 0.5, and the probability of getting tails is also 1/2 or 0.5.
    • The probability of getting heads or tails in multiple flips can be calculated using the concept of independent events.
    • For example, if a coin is flipped 10 times, the probability of getting exactly 5 heads is calculated using the binomial distribution formula.
    • The binomial distribution formula uses the number of trials, the probability of success in each trial, and the number of successes desired to find the probability of getting that number of successes in the given number of trials.
    • In the context of the coin flip example, the trials are the individual flips, the probability of success is 0.5, and the number of successes desired is 5.
    • The probability of getting exactly 5 heads in 10 flips can be calculated using the binomial distribution formula, which gives the probability of getting that specific outcome in the given number of trials.
    • In summary, the probability of getting heads or tails in a coin flip is the same, and it is calculated by dividing the number of successful outcomes by the total number of outcomes. The concept of independent events can be used to find the probability of getting a specific outcome in multiple flips using the binomial distribution formula.- The text discusses the concept of probability in sampling spaces.
    • In the context of an event with a total potential output of 12, the priority of getting a red ball is calculated based on its probability in the sample space.
    • The probability of getting a red ball (out of 12 potential balls) is 7, so the probability of getting a red ball in a draw is 7 out of 12.
    • The text also discusses the calculation of the probability of getting a blue ball, which is 5 out of 12.
    • If an individual event's priority needs to be calculated, the formula needs to be applied to calculate the probability.
    • The concept of probability is extensive, including concepts like Edwardian theorem, multiplication theorem, and basic theorem.
    • These concepts apply to various independent and dependent conditions.
    • In the context discussed, only basic information about probability concepts has been provided.
    • Probability concepts can be understood in depth through concepts like Edwards' theorem, multiplication theorem, and Bayes' theorem.
