Question

a spinner has 7 red spaces, 17 blue spaces, and 11 green spaces. find the theoretical probability of the spinner landing on a red space. p(r) = ? round your answer to the nearest hundredth.

Explanation:

Step1: Calculate total spaces

$7 + 17+11=35$

Step2: Calculate probability of red

$P(R)=\frac{\text{Number of red spaces}}{\text{Total number of spaces}}=\frac{7}{35} = 0.20$

Answer:

$0.20$
