WebOne way to achieve this is to find the percentiles of each student's score. Score 10 is 25 %, score 50 is 50 %, and so on. Note that the percentile is just the CDF. So the CDF of a sample is "uniform". When X is a random … WebThe discrete uniform(0, 1) distribution is a Bernoulli(0.5) distribution. The reason is that we only have two choices, each with probability 0.5. If the first choice is a "failure" and the second choice a "success", we have the definition of a Bernoulli(0.5) random variable. i always stand by your side
