# Question: A study of the nutritional value of a certain kind

A study of the nutritional value of a certain kind of bread shows that the amount of thiamine ( vitamin B1) in a slice may be looked upon as a random variable with µ = 0.260 milligram and s = 0.005 milligram. According to Chebyshev’s theorem, between what values must be the thiamine content of

(a) At least 35/36 of all slices of this bread;

(b) At least 143 144 of all slices of this bread?

(a) At least 35/36 of all slices of this bread;
