Question

Your drawer contains 10 red socks and 7 blue socks. It's to dark to see which are which,but you grab two anyway.What is the probability that you get one of each color?

Answer 1

P(both red)=(10/17)(9/16)
P(both blue)=(7/17)(6/16)

P(both same)= sum of above 2 = (90+42)/(16*17)=132/(16*17)=0.485

coz both same means  both blue or both red

Answer 2

00. 1°/. Because

Red: 10/17×100=58. 8°/.
Blue: 7/17×100=41. 1°/.

Probability: 58. 8+41. 1=99. 9°/.
100. 0-99. 9=00. 1°/.
