To find the toy company stock price, subtract $30 from the restaurant stock price, because the restaurant stock is worth $30 more than the toy company stock. This gets you $4.50.
The probability that a randomly selected carton has a puncture or a smashed corner is 12.6%.
In this problem, the events are:
Event A: Puncture.
Event B: Smashed corner.
The "or" probability is given by:
∩
5% have a puncture, hence
8% have a smashed corner, hence
0.4% have both a puncture and a smashed corner, hence
Then:
Therefore, The probability that a randomly selected carton has a puncture or a smashed corner is 12.6%.
