Answer:
<u></u>
Explanation:
The table that shows the results and the question (taken from similar question) are:
<em>Number Showing Frequency</em>
<em>on Top Face</em>
<em> 1 0</em>
<em> 2 3</em>
<em> 3 3</em>
<em> 4 6</em>
<em> 5 3</em>
<em> 6 5</em>
<em />
<em>Based on these results, what is the experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face? </em>
<h2 /><h2>Solution</h2><h2 />
The frequencies of each event recorded for a particular experience are named<em> experimental probabilities</em> and, in general, differ from the theoretical probabilities.
Experimental probabilities, for instance, when compared with the theoretical probabilities, may show a bias, like a loaded (unfair) die.
<em>The experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face </em>is equal to the number of times the die showed a 5 or a 6 on the top face (the frequencies) divided by the number of times the experiment was performed:
- Frequency of 5 on top face: 3
- Frequency of 6 on top face: 5
====
8
- Number of times the experiment was performed: 0 + 3 + 3 + 6 + 3 + 5 = 20
Probability = 8 / 20 = 2 / 5 = 0.4 ← answer
<h2 />
Factor each out:
11: 1*11
39: 3*13
35: 5*7
8: 2*2*2
since you can see no common factor just multiply them all to get 120120
In this graph, we see Chelsea types 50 words per minutes.
To find the answer, I will use tree diagram:
50 words in 1 minute
175 words in ?minutes
Step 1:
Cross multiply
175×1=175
Step 2:
Use division
175÷50=3.5 or 3 1/2 minutes. As a result, Chelsea types 175 words in 3.5 minutes or 3 1/2 minutes. Hope it help!
