Considering the given discrete probability distribution, it is found that the expected share is of 10%.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution is given by:
Hence the expected value is given by:
E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.
The expected share is of 10%.
