Question

1. Assume that X is a normally distributed random variable with mean 50 and standard deviation 7. Compute the probabilities P(X<35) and P(X>35). In each case, draw a separate normal curve which depicts the area you are computing.
2. Suppose X represents a binomial random variable with n=100 and the probability of success 0.6. Approximate the probability that x=25 by using a normal distribution.
