There are 200 balls of the same size inside a dark room. there are 100 white balls, 55 red balls, and 45 black balls. if one student picks up a ball randomly, what is the probability that he picks up a red ball?

answer choices
22.5%
27.5%
45%
55%

i believe the correct answer would be 27.5 because 100 is already half of 200 and 55+45 is the other 100 and 55/100=27.5

Option 2 is correct.

Step-by-step explanation:

We have been given

Total number of balls: 200

Number of white balls: 100

Number of red balls: 55

Number of black balls: 45

To get in percentage multiply it by 100.

We get 27.5%

Therefore, Option 2 is correct.
