you flip a coin. what is p(tails)? 30% 40% 70% 50%

Explanation:

Step1: Identify total outcomes

A coin has 2 sides (heads and tails), so total outcomes = 2.

Step2: Identify favorable outcomes

Favorable outcome (tails) = 1.

Step3: Calculate probability

Probability formula is $P=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$. So $P(\text{tails})=\frac{1}{2}= 0.5 = 50%$.

Answer:

D. 50%
