In a horse race, the odds that Romance will win are listed as 2 : 3 and that Downhill will win are 1 : 2. What odds should be given for the event that either Romance or Downhill wins? (3 mks)

Respuesta :

Answer:

7:6

Step-by-step explanation:

The odds that Romance will win are listed as 2 : 3

We can rewrite this as:

The probability that Romance will win [tex]=\dfrac23[/tex]

The odds that Downhill will win are 1 : 2.

The probability that Downhill will win [tex]=\dfrac12[/tex]

Therefore:

The probability that either Romance or Downhill wins

=P(Romance Wins)+P(Downhill wins)

[tex]=\dfrac23+\dfrac12\\=\dfrac{2(2)+3(1)}{6}\\=\dfrac76[/tex]

Therefore. the odds that should be given for the event that either Romance or Downhill wins is: 7:6
