Question

if you roll one die, what is the probability of getting an odd number or a 4?
$\frac{2}{3}$
$\frac{1}{2}$
$\frac{1}{3}$
$\frac{1}{3}$

Explanation:

Step1: Identify total outcomes

A die has 6 faces, so total possible outcomes = 6.

Step2: Identify favorable outcomes

Odd numbers on a die are 1,3,5; plus 4. Favorable outcomes: {1,3,5,4}, count = 4.

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}$ = $\frac{4}{6}$ = $\frac{2}{3}$

Answer:

$\frac{2}{3}$
