Do You Need Statistics Help

[Asad.Babur]

Cud anyone please answer question 6 part (I)
http://papers.xtremepapers.com/CIE/Cambridge International O Level/Statistics (4040)/4040_w10_qp_21.pdf

Ok Fine,



(i) For Throwing at first turn, Simply he got
0.2 of Probability


For Second, he Must Fail at First Turn so,
0.8 (Fail) x 0.2 (Hit) = 0.16


For Third, He Definatly must fail two times first.
So 0.8 (Fail) x 0.8 (Fail) x 0.2 (Hit) = 0.128

I Guess it Helps,
Best of Luck

Welcome,

About Calculators, I say The Basic Four and The SQUARE ROOT Function could be alowed

Yea me too
And also when solving aggregate I dexes is it important to write the formula as well
Like are there marks for that as well?

Ofource, You will be unless missing marks.

As, Suitable it is ... Less Chance of Loosing marks

Well they have asked the what the stake will be for this game to be fair
Expected winnings=stake for game to be fair

Expected winnings=submission[winning prize × P(winning prize)]

So [(10×0.2)+(5×0.16)+(5×0.128)]= $3.44

For This You must be able to Calculate Expected Value...



First : Multiply Each Award by it Probability. And Sum up all Results
(0.2 x 10) + ( 0.16 x 5 ) + ( 0.128 x 5 ) + (0.512 x 0) = 3.44 $


Idea of a Fair Game is, That how much you Should pay to make the game fair

here the Expected Value is What to be Paid, Making the game fair .....





I Guess it works

Great

 

[black widow]

Sure I can

Well if u preparing flr stats using the dean chalmers book it is in the end of the probability chapter

Now in such games mostly played in casinos and kther places kn america, people tend to do this to earn money, so obviously they want a profit even if they lose

Like a player gives $16 to play a game in which he/she rolls a die (money given to lay game is called STAKE

If he obtains a certain no. (6) he/she is given $30,

Now he/she might think that if they win they will obtain like double of what they paid but it is not like that

His/her expected winnings is found by the formula below

EXPECTED WINNINGS=[PRIZE ×P(WINNING PRIZE)]

The probability that he/she gets a 6 is 1/6

So, expected winnings=30×(1/6)=$5

Thus the stake must be $5 to make the game fair because the organkzer is gaining a profit

Profit=stake-expected winnings
=16-5=$11

Hope u understand it =))
