Question

you spin the spinner once.
what is p(odd or less than 5)?
write your answer as a fraction or whole number.

Explanation:

Step1: Identify total outcomes

Total sections = 4, so total possible outcomes: $n(S)=4$

Step2: Define event sets

Odd numbers: $\{3,5\}$; numbers <5: $\{3,4\}$

Step3: Find union of events

Combined unique values: $\{3,4,5\}$, so $n(\text{odd or <5})=3$

Step4: Calculate probability

Probability = $\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$
$\text{P(odd or less than 5)}=\frac{3}{4}$

Answer:

$\frac{3}{4}$
