Question

Suppose you toss a fair coin n times, and record the number of
heads that land. Assume that n is large and approximate the discrete
random variable X with a continuous random variable that is
normally distributed with μ = n/2 and σ = √n/2. If n = 400,
find the given probabilities. "a. P(190 ≤ X < 210) b. P(X< 170)
c. P(X > 220) d. P(X = 300)"

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
