Step-by-step explanation:
<h2>Analytic View:</h2>
If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:
![P(A)= \frac{A}{A+B}](https://tex.z-dn.net/?f=P%28A%29%3D%20%5Cfrac%7BA%7D%7BA%2BB%7D)
or probability of its failing is:
![P(B)=\frac{B}{A+B}](https://tex.z-dn.net/?f=P%28B%29%3D%5Cfrac%7BB%7D%7BA%2BB%7D)
<h3>Example:</h3>
Rolling a number smaller than 3 in a dice.
A= 2 (1,2)
B = 4 (3,4,5,6)
![P(A)= \frac{2}{2+4}=\frac{1}{3}](https://tex.z-dn.net/?f=P%28A%29%3D%20%5Cfrac%7B2%7D%7B2%2B4%7D%3D%5Cfrac%7B1%7D%7B3%7D)
<h2>Relative Frequency View:</h2>
Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.
<h3>Example:</h3>
A batter has 50 safe hits at 200 bats, which makes his batting average
which is the probability.
<h2>Subjective View:</h2>
When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.
<h3>Example:</h3>
A person beleives that probability that the batter will hit safely in the next bat is 0.75
Answer:
Not sure which ratio you need, but 6/9 = 2/3
Step-by-step explanation:
1.5xsalmon=swordfish
$39 = 2lb salmon and 3lb swordfish
1lb salmon=$6 6+6 = 12
1lb swordfish=$9 9+9+9 = 27
12+27 = 39
It is true because u need to sort it so u can find the one that cost the most.
Answer:
BD = √13cm, AC = 10c,
Step-by-step explanation:
![AB^2 = AD^2 + BD^2\\\\49 = 36 + BD^2\\\\BD = \sqrt{49 - 36} = \sqrt{13}cm\\\\AC^2 = AD^2 +DC^2\\](https://tex.z-dn.net/?f=AB%5E2%20%3D%20AD%5E2%20%2B%20BD%5E2%5C%5C%5C%5C49%20%3D%2036%20%2B%20BD%5E2%5C%5C%5C%5CBD%20%3D%20%5Csqrt%7B49%20-%2036%7D%20%3D%20%5Csqrt%7B13%7Dcm%5C%5C%5C%5CAC%5E2%20%3D%20AD%5E2%20%2BDC%5E2%5C%5C)
![=36 + 64\\=100](https://tex.z-dn.net/?f=%3D36%20%2B%2064%5C%5C%3D100)
![\\AC = \sqrt{100} = 10cm](https://tex.z-dn.net/?f=%5C%5CAC%20%3D%20%5Csqrt%7B100%7D%20%3D%2010cm)
