These questions will help you develop your understanding of spatial relationships and problem-solving skills in Coordinate Geometry.
Statistics and Probability: Important Questions
In degree 1st year 1st sem maths , z are crucial topics that deal with the analysis of data and the study of chance events. Here are some important questions to focus on:
Statistics:
- Calculate the mean, median, and mode of a set of data
- Find the standard deviation and variance of a set of data
- Solve problems involving frequency distributions and histograms
- Calculate the probability density function (pdf) and cumulative distribution function (cdf) of a continuous random variable
- Solve problems involving linear regression and correlation coefficient
Probability:
- Find the probability of an event using the formula P(A) = number of favorable outcomes / total number of outcomes
- Solve problems involving independent events, dependent events, and conditional probability
- Find the probability of two or more events occurring together
- Solve problems involving Bayes’ theorem and conditional probability
- Identify the difference between a sample space, event, and trial
Important Formulas:
- Mean: μ = (Σx) / n
- Median: Median = middle value of the dataset when it is sorted in order
- Mode: mode = most frequent value in the dataset
- Standard Deviation: σ = √[(Σ(x – μ)^2) / (n – 1)]
- Variance: σ^2 = [(Σ(x – μ)^2) / (n – 1)]
Mastering these concepts and formulas will help you develop a strong foundation in Statistics and Probability, which are essential for many fields including engineering, economics, medicine, and more.
