Hi MIIF, and welcome to MHB!MIIF said:I tried to answer it and got 3/4 or 6/8 after using the union set operation for 4/8 or 1/2 and 3/8, based on what is being asked in the problem. https://www.mathplanet.com/education...lity-of-events

I agree with you. The answer should be 3/4, which is not listed among the choices A.-D.
The probability of a spin resulting in an even number or a number less than 4 is 50%. This means that out of all possible outcomes, half of them will be even numbers or numbers less than 4.
The probability of spin is calculated by dividing the number of desired outcomes by the total number of possible outcomes. In the case of even numbers and numbers less than 4, there are 3 desired outcomes (2, 4, 6) out of 6 possible outcomes (1, 2, 3, 4, 5, 6), resulting in a probability of 3/6 or 50%.
No, the probability of spin is not the same for all numbers. It depends on the specific criteria set for the desired outcomes. In this case, the criteria are even numbers or numbers less than 4, which results in a 50% probability. If the criteria were different, the probability would also be different.
Yes, the probability of spin can change depending on the factors that affect the outcome. For example, if the spinner is biased towards certain numbers, the probability of those numbers appearing will be higher. However, if the spinner is fair and all numbers have an equal chance of appearing, the probability will remain the same.
The concept of probability is used in many real-life situations, such as gambling, weather forecasting, and risk assessment. In these situations, the probability of a certain outcome is calculated based on the available information and can help make informed decisions.
