According to World Health Organization (WHO), in a healthy diet, adults (25 years and older) should gain 72 grams of protein on average per day. We can assume that daily protein intake has a bell-shaped distribution with a standard deviation of 18  in a life of a random adult person. If we have a group of 81 adults,  what is the probability that this group of adults could have more than 70 grams of protein intake?       .1587     .8413     .2257     .5630
