make a spinner with 2 colours. make it so that when the pointer is spun,the probability of landing on black is zero
Which two colors will you choose?
make the two colors anything except black.
To create a spinner with two colors where the probability of landing on black is zero, you will need to allocate the probabilities accordingly. Here's how you can achieve it:
1. Start by understanding that probabilities are expressed as fractions or percentages. In this case, you want the probability of landing on black to be zero, which means the entire probability will be allocated to the other color.
2. Assign a fraction or percentage to represent the probability of landing on the non-black color. Let's assume you want to use red as the other color.
3. Calculate the total probability. Since the probability of landing on black is zero, the probability of landing on the non-black color will be 100%. So, the total probability is 100%.
4. Now, divide the total probability equally among both colors. Since there are only two colors, each color will receive 50% of the total probability.
5. Use a proportional representation to create the spinner. You can divide the spinner into two sectors, each of which occupies 50% of the area.
By following these steps, you will create a spinner where the pointer, when spun, will have no chance of landing on the black color.
