Let x be a random variable that represents the height, in inches, of an adult (18 years old or older) female in the U.S. Then x has an approximate normal distribution with mean μ=63.5 and standard deviation σ=3. Find the probability that a randomly chosen adult female in the U.S is at most 66 inches tall. Hint: you must find P (x≤66)
