646,780 times 547,890 is 354,364,294,200.
Answer:
Step-by-step explanation:
It's too bad about this problem. It's a fair game if you get paid the same amount that you have to pay if you lose.
You win 2 ways
- H - H
- T - T
- Probability 1/2
You lose 2 ways.
- H - T
- T - H
- Probability 1/2
Expectation
E = 1/2 * 3 - 1/2 * 4
E = 1.5 - 2
E = -0.5
Which means that you should expect to lose 0.5 dollars every time you play this dreadful game.
14.5% = 0.145 = 145/1000
14.5 = 14500/1000
So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.
2(w-8) = 9. Hope it helps!
