you spin the spinner once. what is p(less than 3)? write your answer as a fraction or whole number.
Answer
Explanation:
Step1: Identify favorable outcomes
The numbers less than 3 on the spinner are 1 and 2. So there are 2 favorable outcomes.
Step2: Identify total outcomes
The spinner has 4 sections numbered 1 - 4, so there are 4 total outcomes.
Step3: Calculate probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{less than 3})=\frac{2}{4}$.
Step4: Simplify the fraction
$\frac{2}{4}=\frac{1}{2}$
Answer:
$\frac{1}{2}$
