a company makes batteries for cameras. in a new batch of 800 batteries, 32 are not fully charged. based on this batch, what is the probability that a battery is not fully charged? write the probability as a percent.

Answer

Explanation:

Step1: Recall probability formula

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

Number of not - fully - charged batteries (favorable outcomes) = 32, total number of batteries = 800. So probability = $\frac{32}{800}$

Step3: Simplify the fraction

$\frac{32}{800}=\frac{32\div32}{800\div32}=\frac{1}{25}$

Step4: Convert to percentage

$\frac{1}{25}\times100% = 4%$

Answer:

4%
