A rack of 15 billiard balls is shown. If one ball is selected at random, determine the odds against it containing a number grea

andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

A probability is the number of desired outcomes divided by the number of total outcomes.
An odd is the number of desired outcomes divided by the number of non-desired outcomes.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, 6 are less than 7(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

There are 6 desired outcomes.
There are 9 non-desired outcomes.

The odd is:

$\frac{6}{9} = \frac{2}{3}$

The odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

£70 is divided between Natasha, Richard & Stephen so that Natasha gets twice as much as Richard, and Richard gets three time

Mekhanik [1.2K]

Answer:

£42

Step-by-step explanation:

The ratio of Richard's amount to Stephen's amount is ...

R : S = 3 : 1

The ratio of Natasha's amount to Richard's amount is ...

N : R = 2 : 1 = 6 : 3

Then the ratio of all three amounts is ...

N : R : S = 6 : 3 : 1

The proportion of the total that Natasha gets is ...

6/(6+3+1) = 6/10

so she gets ...

(6/10)×£70 = £42

Natasha gets £42.
