Consider the random variable D = R - B. That’s D for “difference.” If all 240 rolls show blue faces, then D = -240; if they all show red faces, then D = 240; otherwise D is somewhere in between. The random variable D is the sum of 240 draws at random with replacement from

thanks Anonymous i done that i need the answer to the first problem part C
TRY 0.078
NO ITS WRONG PLZ COMON GUYS
0.5455
0.1818
which one is wrong? 0.5455 or 0.1818? Let me try the other one.
0.5455 is wrong
0.1818 because
1) (0.05+0.05)/0.55=0.181818
we should remember THAT in first case "eagle" taxcheaters ALSO INCLUDED!
0.1818 is the correct one
