The two-way table below records the distribution of all 2050 trees in the plot by species and by life stage. The distinction between live and sapling tree is made for live trees taller or shorter than 1.3 meters respectively.

	Dead	Live	Sapling
Western red cedar (RC)	.02	.10	.08
Douglas Fir(DF)	.16	.16	.00
Western hemlock (WH)	.23	.21	.04

What is the probability that the selected tree is either Douglas Fir or Live?
What is the probability that the selected tree is either RC or DF?
What is the conditional probability that a randomly chosen tree is sapling, given that it is western hemlock (WH)?
