3 If 90% of the population is right-handed, how many people in a group of 200 would you expect to be right-handed? a 180 b 90 c 20 d 18​

Answer 1

20 because if 90/100 would be right handed then 180/200 would be right handed and then 20/200 would be left handed

Answer 2

Answer:

90% are right handed.

It means (100%-90%)10% are left handed.

Then,10% of 200 are 20

Therefore, I would expect 20 people to be left handed.
