Answer:
A) 0.15
B) 0.36
Step-by-step explanation:
First Box consist 1 red pills and 19 blue pills
second box consist 6 red pills and 14 blue pills
Third box consist 2 red pills and 18 blue pills
a) Prob ( randomly chosen pill is red) ![= \frac{1}{3} \times \frac{1}{20} + \frac{1}{3} \times \frac{6}{20} + \frac{1}{3} \times \frac{2}{20}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B20%7D%20%2B%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cfrac%7B6%7D%7B20%7D%20%2B%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cfrac%7B2%7D%7B20%7D)
![\frac{1}{60} (1+6+2) = 0.15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B60%7D%20%281%2B6%2B2%29%20%3D%200.15)
b)Prob ( 1 reds and 10 blue pilss) =![\frac{1}{3} \frac{^1C_1\times ^{19}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^6C_1\times ^{14}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^2C_1\times ^{18}C_{10}}{^{20}C_{11}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%5Cfrac%7B%5E1C_1%5Ctimes%20%5E%7B19%7DC_%7B10%7D%7D%7B%5E%7B20%7DC_%7B11%7D%7D%20%2B%20%5Cfrac%7B1%7D%7B3%7D%20%5Cfrac%7B%5E6C_1%5Ctimes%20%5E%7B14%7DC_%7B10%7D%7D%7B%5E%7B20%7DC_%7B11%7D%7D%20%2B%20%5Cfrac%7B1%7D%7B3%7D%20%5Cfrac%7B%5E2C_1%5Ctimes%20%5E%7B18%7DC_%7B10%7D%7D%7B%5E%7B20%7DC_%7B11%7D%7D)
![= \frac{1}{3} 1.106 = 0.368](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B3%7D%201.106%20%3D%200.368)
