There are 32 chocolates in a box, all identically shaped. there 12 are filled with nuts, 11 with caramel, and 9 are solid chocolate. you randomly select one piece, eat it, and then select a second piece. find the probability of selecting 2 solid chocolates in a row.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
