Answer:
16/25
Step-by-step explanation:
We just have to find the probability that the 8 non-defects are chosen.
1. Chance first defect is undetected: 8/10 = <em>4/5</em>
2. Chance second defect is undetected: <em>4/5</em>
3. Total probability': 4/5 * 4/5 = 16/25
Think of absolute value and inverse operation, +72 to 72 and 24

Answer:
B, B
Step-by-step explanation:
A model of 9/12 will have 12 parts, 9 of which are shaded.
A model of 3/4 will have 4 parts (1/3 as many), 3 of which are shaded. Each part of this model will correspond to 3 parts of the 9/12 model. Hence, each part is 3 times the size of a part in the 9/12 model.
B) 1/3 times as many
B) 3 times the size
