Question

what is the theoretical probability of flipping heads on a coin?
a. 1.0
b. 0.75
c. 0.33
d. 0.5

Explanation:

Step1: Determine total outcomes

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

Step2: Determine favorable outcomes

Flipping heads is 1 favorable outcome, so \( n(E) = 1 \).

Step3: Use probability formula

Probability \( P(E)=\frac{n(E)}{n(S)}=\frac{1}{2}=0.5 \).

Answer:

d. 0.5
