(A) Consider a communication system where the number of successful transsions out of 10 trials follows a binomial distribution. The success probability for each triat is 0,95, Let X be the random variable representing the number of successful transmissions. -Sketch the cumulative distribution function (CDF) of the distribution. 2- Find Skewness coefficients and check if the distribution is symmetrical or skewed to the right or left. 3- Find kurtosis coefficients, Check if the distribution is mesokurtic, leptokurtic or platykurtic. 4- Find the probability of getting at most eigh. successful transmissions. 5- Find the probability P(20 with a mean 2-1 calculate the probability that the noise is greater than 3 units.
