WebA continuous random variable X follows a normal distribution if it has the following probability density function (p.d.f.):. The parameters of the distribution are m and s 2, where m is the mean (expectation) of the distribution and s 2 is the variance. We write X ~ N(m, s 2) to mean that the random variable X has a normal distribution with parameters …WebWe know that the probability P(X > 75) is equal to 1 – P(X ≤ 75), so we can use a table to find P(X ≤ 75). This result is equal to P(Z ≤ 0.5) (where Z is the standardized random variable). The table states that P(Z ≤ 0.5) = 0.6915 Now we can calculate P(X > 75). P(X > 75) = 1 – P(X ≤ 75) = 1 – P(Z ≤ 0.5) = 1 – 0.6915 = 0.3085<π 3) for f(x)="x2" cos x3 question_answer q: randomly choosing a number from the multiple of 5 between 21 and 49how to create a usps scan form on etsy
