Answer:

a) 2 matches dawn

b) Dunross won that game

c) Yes we can determine the results of all matches ( see step by step explanation)

Step-by-step explanation:

Let call Acadia team ( team A ) Brextone team ( team B ) Cremore team ( team C) and Dunross team (team D)

As each team play each other once, the the games were:

A     plays    vs   B     C     and    D

B     plays     vs          C     and    D

C     plays     vs                            D

A won    one match   and draw  other and lost the other   so made 4 points

B  did the same   4 points

C  got drawn in  two games and lost the third   total of  2 points

D won 2 games and lost  2       total    of  6 points

a) A had one match  drawn

   B had one match  drawn

   C had  two match drawn

Then we have a total of two matches drawn

b) Dunross won that game

c) If B  beat  D   we can determine the others results

as follows

C  lost the game with  D  and drawn with  A  and  B

D  won game with C , lost the game with B and won the game with A

A  lost the game with D , drawn a game with C and won the game with B

B  Lost the game with A , drawn the game with C and, won the game with D

In a clinical study, volunteers are tested for a gene that has been found to increase the risk for a disease. The probability th
MrRa [10]

Answer:

a) 0.984

b) 20 people

Step-by-step explanation:

a)

If The probability that a person carries the gene is 0.1, then in a sample of 20 people, 2 should carry the gene.

Now, we want to know how many samples there are with this property.

Since we have 20 elements where 18 are alike (do not carry the gene) and 2 are alike (carry the gene), we have to compute the number of permutations of 20 elements in which 18 are alike and 2 are alike. This number is

\frac{20!}{18!2!}=190

In this 190 20-tuples there are only 3 where the 2 carriers of the gene are in the first 3 places, namely

(1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)

(1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)

(0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)

where 1=carries the gene, 0=does not carry the gene.

So there are 190-3 = 187 elements in which the first 3 elements have no 2 carriers, hence the probability that 4 or more people will have to be tested until 2 of them with the gene are detected is 187/190 = 0.984 (98.4%) rounded to three decimal places.

b)

Given that the probability that a person carries the gene is 0.1, then in a sample of 20 people, 20*0.1 = 2 should carry the gene.

Step-by-step explanation:

6/5 = x/3

Use cross products

6*3 = 5*x

18 = 5x

Divide each side by 5

18/5 = 5x/5

18/5 =x
