Answer:
C. 0.30
The probability is 0.30
Step-by-step explanation:
The diagram used in solving this question is attached.
From the given graph that is attached: the needed region have
height = 0.5
width = 124.7 - 124.1 = 0.6
The area of the rectangular region is:
[tex]= l * b\\= 0.6 * 0.5\\= 0.3[/tex]
Therefore, the probability of a random voltage between 124.1 and 124.7 is 0.3
