Answer:
A. Yes, the table shows a probability distribution.
Step-by-step explanation:
In a probability distribution, none of the values can be negative or over 1. Additionally, all of the values must sum to 1.
Our probabilities are:
0.087; 0.328; 0.416; and 0.169. None of these are negative and none are over 1.
0.087+0.328+0.416+0.169 = 1.00; this means that this is a probability distribution.
The formula is <span>base × height / 2
So 8.7 x 15.6=135.72 / 2= 67.86
