If you could answer both, I'd be grateful. I'll give a thumbs up, thanks. Only a brief explanation is needed.

Large black-tailed gulls usually layr one to three eggs, and rarely have a fourth egg clutch. It is thought that clutch sizes are limited by how effectively parents can incubate their eggs. Suppose that on average, gulls have a 33% of laying 1 eggr 24.9% of laying 2 eggs, 31.1% chance of laying 3 eggs, and 11% chance of laying 4 eggs. What is the expected value of the number of eggs laid by a random sample of 100 gulls? Round your answer to five decimal places. Answer: The number of different mammal species observed along a transect through a forest is a random variable X with CDF 0.01, i =0 0.16, i = 2 F; = 0.36, i = 8 0.71, i = 11 0.96, i = 19 i = 23 What is the expected value of the random variable X?
