Question

you spin the spinner once. what is p(less than 4 or prime)? write your answer as a percentage rounded to the nearest tenth.

Explanation:

Step1: Identify favorable outcomes

Numbers less than 4 are 3. Prime numbers are 3, 5. The set of numbers that are less than 4 or prime is {3, 4, 5}. There are 3 favorable outcomes.

Step2: Calculate total outcomes

There are 3 sections on the spinner, so total outcomes = 3.

Step3: Calculate probability

$P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{3}{3} = 1$.

Step4: Convert to percentage

$1\times100\%=100.0\%$

Answer:

$100.0\%$
