Question

The table shows the color preferences of 50 shoppers at the mall. What is the probability that one shopper, selected at random from the 50 surveyed, preferred the color red or blue? Red 7, yellow 3, blue 13, green 15, orange 12. I think it is 2/5

Answer 1

20/50=2/5=0.4=40%
So yeah, 2/5 or 0.40 or 40%
They're all equal.
Hope this helps.

Answer 2

Answer: There is probability of getting red or blue is 40%.

Explanation:

Since we have given that

Number of preferences for red = 7

Number of preferences for yellow = 3

Number of preferences for blue = 13

Number of preferences for green = 15

Number of preferences for orange = 12

Total number of preferences = 50

So, Probability of getting red or blue is given by

P(Red) + P(Blue)

`=(7)/(50)+(13)/(50)\\\\=(20)/(50)\\\\=(2)/(5)\\\\=0.4\\\\=40\%`

Hence, there is probability of getting red or blue is 40%.
