Python nests How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. Nest temperature Cold Neutral Hot Hatching status Hatched 16 38 75 Didn't hatch 11 18 29 a. P(did not hatch or cold) b. P[hatched or warm) c. P(hatched I neutral) d, P(did not hatch or hot)
