Answer:
(in tabular format)
<em />
<em>x 1 5 10</em>
<em>p(x) 0.4 0.3 0.3</em>

Step-by-step explanation:
probability mass function (PMF) gives us probabilities of possibilities of a random variable. It is usually shown in a tabular format with Random Variable (x) in one column and each associated probability [P(x)] in its respective column.
Here, our random variable is the yearly revenues of being "very successful", "moderately successful", and "unsuccessful".
So we can write [in probability notation]:
P(x=10) = 0.3
P(x=5) = 0.3
P(x=1) = 0.4
This, in tabular format would be the probability mass function (PMF).
<em>x 1 5 10</em>
<em>p(x) 0.4 0.3 0.3</em>
Answer:
3. 15 units
Step-by-step explanation:
When medians intersect, the point of intersection divides the median into parts in the ratio 2:1. That is ...
OC : CR = 2 : 1 = 4 units : 2 units . . . . . . OR = (4+2) units = 6 units
MC : CT = 2 : 1 = 6 units : 3 units . . . . . . MT = (6+3) units = 9 units
The sum of lengths OR + MT is ...
6 units + 9 units = 15 units
