you flip a coin. what is p(tails or heads)? write your answer as a percentage.

Explanation:

Step1: Recall probability formula for mutually - exclusive events

For mutually - exclusive events (A) and (B), (P(A\cup B)=P(A)+P(B)). When flipping a coin, the event of getting tails ((T)) and the event of getting heads ((H)) are mutually - exclusive.

Step2: Determine individual probabilities

The probability of getting tails (P(T)=\frac{1}{2}), and the probability of getting heads (P(H)=\frac{1}{2}).

Step3: Calculate (P(T\cup H))

(P(T\cup H)=P(T)+P(H)=\frac{1}{2}+\frac{1}{2}=1).

Step4: Convert to percentage

To convert the probability to a percentage, we multiply by 100. So (1\times100 = 100%).

Answer:

100%
