Question

Please Help as soon as possible 

Answer 1

to find the experimental probability you can just divide the number of defective light bulbs by the total number of light bulbs inspected

15/300 = 0.05

Answer 2

If 15 light bulbs are found to be defective out of 300 that are inspected, that means:

   Ratio of defective light bulbs to examined light bulbs is:

                         15                 /            300

 

This is 15/300 = 1/20.

 

The Experimental Probability (that is, what was observed) is that 1 out of 20 light bulbs is defected.  It is statistically reasonable (within a calculated error) to expect that this probability will continue (approximately) for the larger population of light bulbs (that is, for those not inspected as well).
