Respuesta :
The probability that Elisa does not get a ginger cat is 0.8 or 80%.
What is the probability?
- If a is an event in a sample space S then the probability P(A) = n(A)/n(S), where n(A) is the number of sample points in A and n(S) is the number of sample points in S.
- If A is an event in a sample space S, then the ratio [tex]P(A) : \bar {P(A)}[/tex] is called the odds in favor of A and [tex]\bar {P(A)}:P(A)[/tex] is called the odds against A.
- The probability [tex]\bar {P(A)}=1-P(A)[/tex].
Calculation:
It is given that,
Elisa is going to adopt a kitten. The shelter has 30 kittens.
In which,
Black: 23% = 23/100 × 30 = 69/10
Tabby: 50% = 50/100 × 30 = 15
Calico: 7% = 7/100 × 30 = 21/10
Ginger: 20% = 20/100 × 30 = 6
The event that "Elisa does not get a ginger cat" is the odds against the actual event that "Elisa gets a ginger cat".
So, we can write,
[tex]\bar {P(G)} = 1 - P(G)[/tex]
= 1 - 6/30
= 0.8
Thus, the probability that Elisa does not get a ginger cat is 0.8 or 80%.
