2. A company produces batteries. On average, 83% of all batteries produced are good. Each battery is tested before being dispatched, and the inspector correctly classifies the battery 92% of the time. A. What percentage of the batteries will be "classified as good”?

B. What is the probability that a battery is defective given that it was classified as good?​

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
