Sandy spun a spinner with 5 equal parts labeled 1-5. What is the probability she will NOT spin a 4?
To find the probability of an event, we need to know the number of favorable outcomes and the total number of possible outcomes.
In this case, Sandy spun a spinner with 5 equal parts labeled 1-5. So, the total number of possible outcomes is 5.
However, she wants to know the probability of NOT spinning a 4. To find the number of favorable outcomes, we need to determine how many numbers are NOT 4.
Since there are 5 possible outcomes (numbered 1 to 5), and only 1 of them is a 4, the number of favorable outcomes is 5 - 1 = 4.
Therefore, the probability that Sandy will NOT spin a 4 is 4/5.
