128 full-time workers are selected in a small city. If X is the number of full-time workers who are saving for retirement, then the distribution of X can be approximated with a normal distribution, N(64,5.7), where the mean () is 64 and standard deviation () is 5.7. Using this approximation, find the probability that 67 or 68 full-time workers are saving for retirement. You may use the portion of the Standard Normal Table below.
