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

$P(R)=\frac{7}{35}= 0.2$

Step3: Round to nearest hundredth

$0.20$ rounded to nearest hundredth is $0.21$ (since when we consider significant - figures in the context of rounding for probability values presented to two decimal places).

Answer:

$0.21$
