Question

If 65% of the population have black eyes 25% have brown eyes remaining have blue eyes. What is the probability that a person chosen at random has 1) either blue or brown eye 2)blown or black 3)blue eyes 4)neither blue nor brown eyes ?

Answer 1

hey mate!

here is your answer:

total outcomes=100%

blue eyes=100-(25+65)=100-90=10%

1. favourable outcomes= 10+25=35

probability =35/100=7/20

2. favourable outcomes =65+25=90

probability =90/100=9/10=0.9

3. favourable outcomes =10

probability =10/100=0.1

4. favourable outcomes =25

probability =25/100=1/4
