please answer each parts of question

2A) Consider a portfolio of cancer research projects, and assume for simplicity that each project's financial return has a standard deviation of 400%. If the correlation coefficient between each pair of projects is 0.5, what is the standard deviation of an equal-weighted portfolio of: (Note: Your answer should be a number in percentage form. Do not enter '%'.)

10 projects? ____% 100 projects ___% 1000 projects ____%

2B) Now assume the projects are statistically independent and therefore uncorrelated. What is the standard deviation of an equal-weighted portfolio of: (Note: Your answer should be a number in percentage form. Do not enter '%'.)
