On the multiple choice test there are 25 questions. Each question has eight possible answers. Suppose a student guesses at one answer for all questions on the test. A) (Changed) Define the distribution. (You can use the notation: X~ )

b) Find the probability that the student gets exactly 10 answers wrong. Round to 4 decimal places, if needed.

c) Find the probability that the student gets more than 15 answers wrong. Round to 4 decimal places, if needed.

Ithink the answer is fusion 

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.

Using renewable energy sources. just did the test and got it right.
