X denotes a binomial random variable with parameters n and p, Indicate which area under the appropriate normal curve would be determined to approximate the specified binomial probability. P(7 ≤ X ≤ 10)

x is a binomial random variable,find P(X>=3)

Please be sure to include all relevant work and an explanation please and thank you.  Use the following information to answer the next three exercises: The length of time it takes to find a parking space at 9 A.M. follows a normal distribution with a mean of five minutes and a standard deviation of two minutes. Based upon the given information and numerically justified, would you be surprised if it took less than one minute to find a parking space? Yes No Unable to determine

Assume that the random variable X is normally distributed, with mean u = 60 and standard deviation o=8. Compute the probability P (38 < X < 70) Please show step by step your calculations. Thank you.
