Select all true statements
First, calculate the total observed frequency;
<u>(a): Relative frequency of 4 is 2/9</u>
Relative frequency is calculated by:
For roll 4
So, the relative frequency is:
Simplify
<em>(a) is true</em>
<u>(b): Experimental probability of 3 greater than its theoretical probability</u>
The experimental probability is its relative frequency;
For roll 3
The experimental probability is:
Simplify
To calculate the theoretical probability, w have:
---- sample space
--- number of times 3 occur
The theoretical probability is:
The theoretical probability is experimental probability.
<em>(b) is false</em>
<u>(c): Experimental probability of 2 greater than its theoretical probability</u>
Using the explanations in (b), we have:
For roll 2
The experimental probability is:
Simplify
To calculate the theoretical probability, we have:
The theoretical probability is:
The experimental probability is theoretical probability.
<em>(c) is true</em>
<u>(d): Relative frequency of 5 is 2/13</u>
For roll 5
The relative frequency is:
Simplify
<em>(d) is true</em>
Answer:
It takes 1.5 days for the Kimball family to get to Baltimore
Step-by-step explanation:
Given:
Total distance from the home to Baltimore =
Distance they would travel on each day =
To Find:
How many days it will take the Kimball family to reach Baltimore = ?
Solution:
Lets first convert mixed fraction into fraction
=
=
=
=
=
=
Now,
In one day =
In x day =
By Cross multiplication
x = 1.517
x = 1. 5 days
