The correct answer and explanation is:
It seems you have a multi-part exercise combining probability, combinatorics, and mathematical reasoning. I’ll address the tasks based on the information provided and elaborate on how the probabilities and expected outcomes are calculated. Here’s a detailed breakdown:
1. Insects Falling in Love (Italian Insects Reference)
This part seems humorous and likely symbolic rather than literal. There’s no mathematical answer, but it might imply solving riddles or using wordplay related to “Italian insects.”
2. Spinner Outcomes
Number of outcomes:
If the spinner is divided into equal sections (e.g., numbers 1 through 10):
- Total outcomes: 10
Probabilities:
a. P(Even number)=Even numbersTotal outcomes=510=0.5P(\text{Even number}) = \frac{\text{Even numbers}}{\text{Total outcomes}} = \frac{5}{10} = 0.5
b. P(Odd number)=Odd numbersTotal outcomes=510=0.5P(\text{Odd number}) = \frac{\text{Odd numbers}}{\text{Total outcomes}} = \frac{5}{10} = 0.5
c. If half the spinner is black: P(Black)=0.5P(\text{Black}) = 0.5
3. Expected Outcomes for Spinner
If spun 100 times:
- a. Even numbers: 100×0.5=50100 \times 0.5 = 50
- b. Odd numbers: 100×0.5=50100 \times 0.5 = 50
4. Rolling a 6-Faced Die
Expected Rolls for Specific Number:
Probability for any face (e.g., getting a 4) = 16\frac{1}{6}
- Rolling 1200 times: 1200×16=2001200 \times \frac{1}{6} = 200
5. Probability of Choosing a Cube
Given: Bag contains 12 green, 5 blue, and 3 yellow cubes (total: 20 cubes).
- a. P(Green)=1220=0.6P(\text{Green}) = \frac{12}{20} = 0.6
- b. P(Blue)=520=0.25P(\text{Blue}) = \frac{5}{20} = 0.25
- c. P(Yellow)=320=0.15P(\text{Yellow}) = \frac{3}{20} = 0.15
- d. P(Not blue)=1−P(Blue)=1−0.25=0.75P(\text{Not blue}) = 1 – P(\text{Blue}) = 1 – 0.25 = 0.75
6. Spinner Expected Outcomes
If 600 spins are performed and probabilities are given for specific outcomes (e.g., P(81),P(85),P(810)P(81), P(85), P(810)):
- Multiply P(specific outcome)×600P(\text{specific outcome}) \times 600.
7. Coin Toss Probability
Jill tossed 10 heads. Assuming the coin is fair:
- Probability of heads on next toss = 0.5 (independent events).
8 & 9. Raindrop on Tiles
If a raindrop falls randomly on tiles of different colors:
- Total outcomes depend on the number and layout of tiles.
- P(Falling on a color)=Tiles of that colorTotal tilesP(\text{Falling on a color}) = \frac{\text{Tiles of that color}}{\text{Total tiles}}.
10. Expected Outcomes for Raindrops
For 100 raindrops:
- Multiply P(color)×100P(\text{color}) \times 100 for each color.
Explanation
Probability measures the likelihood of an event occurring. It is calculated as the ratio of favorable outcomes to total possible outcomes. For instance, spinning a fair spinner with equal sections means every section has an equal chance of being selected. Similarly, rolling a die or choosing a cube from a bag relies on assuming equal likelihood unless stated otherwise.
Expected outcomes are predictions based on probability. For example, if the probability of landing on a black tile is 0.4, and a raindrop falls 100 times, the expectation is 100×0.4=40100 \times 0.4 = 40 black tiles.
For independent events, like tossing a coin, the outcome of one event does not affect the other. Even if heads appears 10 times consecutively, the probability of getting heads on the next toss remains 0.5.
Understanding probability helps in making informed predictions in games, experiments, and real-world scenarios, from weather forecasts to decision-making.
