You check 20 batteries.Fourteen do not have a charge.
Part a. What is the experimental probability that the next battery you check does not have a charge?
Part B. Select an answer from each box to make the statement true
If 300,100,240 batteries are tested I would expect 30,210'180 to have a charge which number
14/20 = 7/10 = 0.70
0.70 * 300 = 210
0.70 * 100 = 70
0.70 * 240 = 168
To calculate the experimental probability, you need to divide the number of successful outcomes (batteries without a charge) by the total number of outcomes (total number of batteries checked).
Part a. The experimental probability that the next battery you check does not have a charge is calculated as follows:
Number of batteries without a charge = 14
Total number of batteries checked = 20
Experimental probability = Number of batteries without a charge / Total number of batteries checked
Experimental probability = 14 / 20 = 0.7
Therefore, the experimental probability that the next battery you check does not have a charge is 0.7 or 70%.
For Part B, it seems that some information is missing from your question. You mentioned three different numbers (300, 100, 240), but it is unclear what these numbers are representing. Could you please provide more context or clarify the question?
