Answer:
Coterminal angle of 60° (π / 3): 420°, 780°, -300°, -660°
Step-by-step explanation:
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
1/2x2x6
=1x6
=6
That's your answer.
After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
You are right ! It is 8.246 and so on ;)
