The answer is D. 28, 14/28 = 1/2.
Hope this helps:)
Answer : 3,367
Explanation: 9,009 subtracted from 12,376 is 3,367 meaning that the difference between the phone calls is 3,367 which is how many more phone calls were made this year.
Every point is translated according to the rule ( x, y ) → ( x + 2, y - 6 )
L ( -1, 2 ) → L´ ( -1 + 2, 2 - 6 ) = ( 1, -4 )
Answer:
A. 0.47 ; B. 0.40 ; C. 0.73 ; D. 0.23 & 4.26
Step-by-step explanation:
- Total Animals = Total Possible Outcomes = 8 + 12 + 6 + 5 + 11 = 42
- Probability = No. of Possible Outcomes / No.of total outcomes
- Odds in favour of event = Prob (Event) / Prob (No Event) ; Odds in against event = Prob (No Event) / Prob (Event)
A. Probability of choosing a Cat = All no. of cats / Total no. of animals
= ( 8 + 12 ) / 42 = 20 / 42 = 0.47
B. Probability of choosing a Common Cat or a Labrador Retriever :-
No. of common cats + no.of labrador retrievers / Total Animals
= (12 + 5) / 42 = 17 / 42 = 0.40
C. Probability of selecting non 'mixed breed' dog :-
No. of animals except mix breed dogs / Total Animals
= ( 8 + 12 + 6 + 5 ) / 42 = 31 / 42 = 0.73
D. Probability of choosing Siamese cat = Siamese Cat / Total Animals = 8 / 42 = 0.19 ; Probability Not choosing Siamese Cat = 1 - Prob (Siamese Cat) = 1- 0.19 = 0.81.
Odds in favour of choosing Siamese Cat :-
Prob (Siamese cat) / Prob (Not Siamese Cat) = 0.19 / 0.81 = 0.23
Odds against choosing Siamese Cat :-
Prob (Not Siamese Cat) / Siamese Cat = 0.81 / 0.19 = 4.26
