Question

Transcribed Image Text:2 A company manufactures floor tiles of mean length 20 cm with standard
deviation 0.2 cm. Assuming the distribution of the lengths of the tiles is
normal, find the probability that, when 12 randomly selected floor tiles are
laid in a row, their total length exceeds 241 cm.
