Question

The possible values of the water height H, relative to mean water level, at each of the two rivers A and B are as follows (in meters): H--3, 32, -1, 0, 1, 2, 3, 6. a)-Consider river A and define the following events: A: = { НА > 0 }, А,-{ HA-0 }, and A,-{ HA S0). List all pairs of mutually exclusive events among A, A2, and A3. b)- At each river, define Normal water N--1sHs1), Drought D-H1, and Flood F- H>1). Use the ordered pair (hA, hB) to identify sample points relating to joint water levels in A and B, respectively; thus (3, -1) defines the condition hA 3 and hs-1 simultaneously Determine the sample points for the events: iNA n Ng; ii) (FA U DA)N.
