Question 1:
The probability of selecting a title available in print (either paperback, hardcover, or both) out of the total inventory is:
Probability = 1 - (Number of titles not available in print) / (Total number of titles) = 1 - 7/30 = 23/30
Question 2:
The probability of selecting a title available in both paperback and hardcover out of the total inventory is:
Probability = (Number of titles available in both formats) / (Total number of titles) = 5/30
The probability of selecting a title available in print (either paperback, hardcover, or both) out of the total inventory is:
Probability = 1 - (Number of titles not available in print) / (Total number of titles) = 1 - 7/30 = 23/30
Question 2:
The probability of selecting a title available in both paperback and hardcover out of the total inventory is:
Probability = (Number of titles available in both formats) / (Total number of titles) = 5/30
