Answer:
3rd Option and 4th Option
Step-by-step explanation:
Note: The options to the question is attached as picture below
<u>1st case</u>
Initial deposit (P) = 500
Annual interest rare (r) = 2.5%
Account balance after x years, y = P(1+r/100)×
y = 500(1+2.5/100)×
y = 500(1+0.025)×
y = 500(1.025)× ----- 3rd option
<u>2nd case</u>
Initial deposit (P) = 400
Annual interest rare (r) = 2%
Account balance after x years, y = P(1+r/100)×
y = 400(1+2/100)×
y = 400(1+0.02)×
y = 400(1.02)× ---- 4th option

Calculating 15% of 25, we get:
So, in total 3.75 rivets are DEFECTIVE.
The probability of choosing a defective rivet =
So, there is a 0.15 probability that the rivets chosen is DEFECTIVE.
