Let X be the number of days per week that a randomly chosen first-year college student eats at least one meal on campus. The table shows the probability distribution of X. Number of Days 0 1 2 3 4 5 6 7
Probability 0.05 0.10 0.15 0.20 0.20 0.15 0.10 0.05
What is the probability that a randomly selected first-year college student eats at least one meal on campus at least one day per week?

How do i do this activity, is appreciated

What is the difference between the predicted value and the actual value

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
