Flip a coin three times. You will win $2 for each heads. What is the expected winning (expectation of your winning)

Romashka [77]

The three coins could land any these 8 ways:

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

P(3 heads) = 1 way out of 8 or 1/8

P(2 heads) = 3 ways out of 8 or 3/8

P(1 head) = 3 ways out of 8 or 3/8

P(0 heads) = 1 way out of 8 or 1/8

x=Winnings P(x) E(x)=x�P(x)

$3 1/8 $.375

$2 3/8 $.75

$1 3/8 $.375

-$10 1/8 -$1.25

---------------------------

Total expectation = $ .25

Kenny had 5/7 more trading cards than lee. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee.

svp [43]

Answer:

Step-by-step explanation:

Let X is the number of cards Kenny has

Let Y is the number of cards Lee has

1. Kenny had 5/7 more trading cards than lee, it means

X = Y + 5/7X (1)

2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means:

X + 50%X = Y + 220 (2)

So, we solve the 2 equations to find out X and Y

$\left \{ {{X=Y + 5/7X} \atop {1.5X=Y +220}} \right.$

<=> X = $\frac{3080}{17}$ and Y = $\frac{880}{17}$

<=> X ≈181 and Y ≈ 52
