At least means 6 is included. So, 6 or more is required that translates to “greater than or equal to”.
A beverage manufacturer would like to test the reliability of two processes for manufacturing orange juice and apple cider, respectively. A review of the orange juice manufacturing process found that 10% of the bottles are underfilled. A review of the apple cider manufacturing process found that 15% of the bottles are underfilled.
Orange Juice | Apple Cider | |
Probability of under-fill | 0.10 | 0.15 |
If two cans are selected at random (one from each process), what is the probability of selecting one under filled orange juice bottle and one under filled apple cider bottle?
