Does experimental probability always give the same results? Explain your answer.
Vanyuwa [196]

Answer:

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

Step-by-step explanation:

The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability

Click the score on the graph where you think the<br> balancing point would be for this data.
Ulleksa [173]

Answer:

The balancing point is 23

<em></em>

Step-by-step explanation:

Given

The above graph

Required

Determine the balancing point

This simply means that we calculate the mean.

From the above graph, we have:

\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}

So, the mean is:

\bar x = \frac{\sum fx}{\sum f}

\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}

\bar x = \frac{230}{10}

\bar x = 23

<em>Hence, the balancing point is 23</em>
