this is the practice set for the final. I can't figure out what I'm doing wrong

Consider the following information: Required: (a)What is the expected return on an equally weighted portfolio of these three stocks? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 3216).) (b)What is the variance of a portfolio invested 20 percent each in A and B and 60 percent in C ? (Do not round intermediate calculations. Round your answer to 5 decimal places (e.g., 32.16161).)
