Science > Mathematics > Statistics and Probability > Probability > Binomial Distribution In this article, we shall study to solve problems of probability based on the concept of the binomial distribution. Example – 01: An unbiased coin is tossed 5 times. Find the probability of getting a) three heads b) at least 4 heads Solution: […]
Science > Mathematics > Statistics and Probability > Probability > Normal Distribution 02 In this article, we shall study to find the probability of an event when data normally distributed is given. Area Under Normal Curve (0 < x< z) Example – 01: A sample of 100 dry battery cells tested to find the length […]
Science > Mathematics > Statistics and Probability > Probability > Normal Distribution 01 The normal distribution refers to a family of continuous probability distributions described by the normal equation. on the domain x ∈ (- ∞, ∞) where x is a normal random variable, μ is the mean, σ is the standard deviation, Thus the normal distribution can be completely specified by two […]
Science > Mathematics > Statistics and Probability > Probability > Checking of Probability Mass Function In this article, we shall study to check whether the given function is a probability mass function or not. Example – 01: X = x 1 2 3 4 P(X=x) 0.1 0.2 0.3 0.4 Verify whether the function can be […]
Science > Mathematics > Statistics and Probability > Probability > Probability Distribution In this article, we shall study to write probability mass function and to write probability distribution for the given event. Example – 01: If a coin is tossed two times and X denotes the number of tails. Find the probability distribution of X. […]
