probability

An article in the Los Angeles Times (Dec. 3, 1993) reports that 1 in 200 people carry the defective gene that causes inherited colon cancer. In a sample of 1000 individuals, what is the approximate distribu- tion of the number who carry this gene? Use this distribution to calculate the approximate probabil- ity that
a. Between 5 and 8 (inclusive) carry the gene.
b. At least 8 carry the gene.
