Answer:
25%
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = Expected outcome/Total outcome
Since there are 4 colours to spun (purple, red, green, and yellow)
Total outcome = 4
If purple landed, then the expected outcome = 1
Substitute into the formula;
P(Purple) = 1/4
P(Purple) = 0.25
P(Purple) = 25%
Hence the theoretical probability of landing on purple is 25%
