2 answers:
<h2>Answer:</h2>
Option: C is the correct answer.
The mean of the data set is: 1.6
<h2>Step-by-step explanation:</h2>The mean of the data set is the average value of the data set.
It is calculated as the ratio of the sum of all the data values to the number of data points.
Here we have the data set as:
1.2, 1.8, 1.6, 1.4, 1.4, 2.2
There are a total of 6 data points.
and the sum of these data points is: 1.2+1.8+1.6+1.4+1.4+2.2= 9.6
Hence, the mean of the data set is:

Answer:
probability of an electric power outage shipboard is 0.075 or 7.5 %
Step-by-step explanation:
Given the data in the question;
Probability of engine malfunction = 25% = 0.25
Probability of generator malfunction = 10% = 0.1
Probability of generator being repaired = 50% = 0.5
probability of an electric power outage shipboard = ?
To get the probability of an electric power outage shipboard, we use the expression;
probability of an electric power outage = 2 × p( Probability of generator malfunction ) × p( Probability of generator being repaired ) × ( 1 - p( Probability of engine malfunction ) )
so we substitute in our given values;
probability of an electric power outage = 2 × 0.1 × 0.5 × ( 1 - 0.25 )
probability of an electric power outage = 2 × 0.1 × 0.5 × 0.75
probability of an electric power outage = 0.075 or 7.5 %
