Afina-wow [57]

Answer: −1.409

Step-by-step explanation:

Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013

Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118

Probability of other draw: 1 - 0.013 - 0.118 = 0.869

0.013 * (50 - 5) = 0.585

0.118 * (25 - 5) = 2.353

0.869 * (0 - 5) = -4.347

Expected value: 0.585+ 2.353 - 4.347 = -1.409

Solve 1.8c = 7.5 for c.
igor_vitrenko [27]
1.8c=7.5 \\\\ c=\frac{7.5}{1.8} \\\\ c=\frac{5\frac{5}{10}}{1\frac{8}{10}}=\frac{5\frac{1}{2}}{1\frac{4}{5}} \\\\ c=\frac{\frac{11}{2}}{\frac{9}{4}}= \frac{11}{2}*\frac{4}{9} \\\\ \boxed{c=\frac{22}{9}}
