Answer:
Though it may vary, it's going closer to 0.5 as long as we enlarge our sample.
Step-by-step explanation:
1) Since a coin has heads and tails, then a sample proportion of 40 we can simulate it using some applets.
2) Here are the most common outcomes, as long as we continue on flipping coins.
If we continue enlarging our sample (80, 120,160...) the probability goes closer to 0.5
This shows: the theoretical probability goes closer and closer to the experimental probability of heads and tails
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Ratio of sapphires to emeralds = 3:1
Let the number of sapphires be 3x.
Let the number of emeralds be 'x'.
According to question, if 6 emeralds are added, we get that
So, Number of sapphires = 3×3 = 9
Number of emeralds = 3
So, total emeralds would be 3+ 6 = 9.
Hence, option 'A' is correct.
