Can someone help me and answer these probability problems. Please show your solutions

. Suppose x is normally distributed with a mean of5 and a standard deviation of 0.4. Using the standard score formula, we nd P {x 5 Kg) = P (2 s 1.3}. What is the value of Xo? . What will be the value of P {X 2 235) given that a normal distribution has u = 241 and d = 2? The average hourly wage of workers at a fast food restaurant is P338.10/hr. Assume the wages are normally distributed with a standard deviation of P23.41. Ifa worker at this fast food restaurant is selected at random, what is the probability that the worker earns more than P351.10? . 0n the day before an exam in an online class, students e-mailed questions to the professor at a rate of 1 every 20 minutes, exponentially distributed. Determine the probability that that the interval between succeeding messages is more than an hour. . A normal distribution has a mean of 30 and a standard deviation of 12. What is the probability of selecting a value between 70 and 85
