Question

spinner results
color frequency
red 19
blue 4
green 11
yellow 15
purple 4
based on these results, express the probability that the next spin will land on red or green or yellow as a percent to the nearest whole number.
answer attempt 1 out of 2

Explanation:

Step1: Calculate total frequency

$19 + 4+11 + 15+4=53$

Step2: Calculate frequency of red, green and yellow

$19 + 11+15 = 45$

Step3: Calculate probability as a fraction

The probability $P=\frac{45}{53}$

Step4: Convert fraction to percentage

$P=\frac{45}{53}\times100\%\approx85\%$

Answer:

$85\%$
