Question

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.

Answer 1

The probability that they both were planted alone is 0.3325.

What is genetic probability?

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

• Number of plants planted alone = 134
• P(both plants were planted alone) = 134/232 x 133/231 = 0.3325

So the probability that  both were planted alone is 0.3325.
