Explanation

Let x,2x, and 3x be the measures of the three angles. Then:

x + 2x + 3x = 180

6x = 180

\(x=180 \div 6=30\)

3x = 3(30) = 90

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?
