Biologists would like to catch costa rican glass frogs for breeding. there is a 70% probability that a glass frog they catch is male. if 10 glass frogs of a certain species are caught, what are the chances that they will have at least 2 male and 2 female frogs? what is the expected value of the number of female frogs caught?

The Chances of Frog Gender and Expected Value

A biologist would like to catch Costa Rican glass frogs for breeding.

There is given data which indicates that if 10 glass frogs of a certain species are caught then there are many chances that they will have at least 2 male and 2 female frogs. The expected value of the number of female frogs caught is 2.

The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

The atmosphere does not play an important role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are  solids at the symbolic ranges of temperature and pressure present on Earth.

Thus, the earths spheres like biosphere, Cryosphere  and lithosphere are included in the phosphorus cycle but atmosphere is your answer.
