What can I do A & B (ANSWER ONLY)
What's More A. Construct a probability distribution for the data. 1. The probabilities that a surgeon operates on 3,4,5,6, or 7 patients in any one day are 0.15,0.20 ,0.25,0.20, and 0.20 respectively. 2. The probabilities that a customer buy 2,3,4,5, or 6 items in a convenience store are 0.32,0.12,0.23,0.18, and 0.15 respectively. 3. The probabilities that a student will borrow 1,2,3, or 4 books are 0.45,0.30,0.15, and 0.10, respectively. 4. The probabilities that a bias die will fall as 1,2,3,4,5 or 6 are 11111 2612 12 12 and respectively. 5. The probabilities that a dispositor will invest Php 100,000, Php250,000., or Php180,000 areand;, respectively. What I Can Do A.
