you roll a fair 6 - sided die. what is p(roll an even number)? if necessary, round your answer to 2 decimal places.
Answer
Explanation:
Step1: Identify total outcomes
A 6 - sided die has 6 possible outcomes: 1, 2, 3, 4, 5, 6. So $n(S)=6$.
Step2: Identify favorable outcomes
The even numbers on a 6 - sided die are 2, 4, 6. So $n(A) = 3$.
Step3: Calculate probability
The probability formula is $P(A)=\frac{n(A)}{n(S)}$. Substituting the values, we get $P(A)=\frac{3}{6}=\frac{1}{2}=0.50$.
Answer:
0.50
