Use the sample data below to answer the following question(s). Biologists studying the re-vegetation of two species of succulent plants in the South African desert examined the number of plants that survived depending on whether they were planted in multi-species clumps or planted alone. The following data resulted:

Planted in Planted

Multi-Species Clumps Alone

Number of Species 1 Survived 64 87

Number of Species 2 Survived 34 47

If two different surviving plants are randomly selected, find the probability that they both were species 1.

If two different surviving plants are randomly selected, find the probability that they both were planted alone.
