Final answer:
The probabilities calculated for the respective parts of the question are: (a) 35.8% for a stockholder holding 1000 or more shares, (b) 17.0% for a stockholder holding less than 200 shares and in favor of the merger, (c) 62.3% for holding between 200 to under 1000 shares or being opposed to the merger, and (d) 20.0% for holding under 200 shares given that the stockholder is opposed.
Step-by-step explanation:
The given problem pertains to the field of probability and involves calculating various probabilities concerning stockholders' opinions and the number of shares they hold in a corporation.
a. To find the probability that a stockholder holds 1000 or more shares, we divide the number of stockholders with 1000 or more shares by the total number of stockholders:
Probability (%) = (Number of stockholders with 1000 or more shares / Total number of stockholders) × 100 = (19 / 53) × 100 ≈ 35.8%
b. To find the probability that a stockholder holds less than 200 shares and is in favor of the merger, we look at the joint occurrence for both conditions:
Probability (%) = (Number of stockholders under 200 shares and in favor / Total number of stockholders) × 100 = (9 / 53) × 100 ≈ 17.0%
c. The probability that a stockholder holds between 200 to under 1000 shares or is opposed to the merger involves considering the union of two events:
Probability (%) = ((Number of stockholders with 200 to under 1000 shares) + (Number of stockholders opposed) - (Both conditions overlap) / Total number of stockholders) × 100 = ((17 + 25 - 9) / 53) × 100 ≈ 62.3%
d. Finally, to find the probability that a stockholder holds under 200 shares, given that they are opposed to the merger, we use conditional probability:
Probability (%) = (Number of stockholders under 200 shares and opposed / Number of stockholders opposed) × 100 = (5 / 25) × 100 = 20.0%
