1.A seed randomly blows around in a complex habitat. It may land on any of three different soil types: H - a high-quality soil that gives an 85% chance of seed survival,

M - a medium-quality soil that gives a 40% chance of survival, and L - low-quality soil that gives a 15% chance of survival. The three soil types (H, M, L) are present in the habitat in proportions of 5:3:2, respectively. The probability that a seed will land on a particular soil type is proportional to the frequency of that type in the habitat.

L = Lands; L' - Dies before landing; S = Survives; S' - Does not survive
