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:
or probability of its failing is:
<h3>Example:</h3>
Rolling a number smaller than 3 in a dice.
A= 2 (1,2)
B = 4 (3,4,5,6)
<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
K= 100
You use distributive property
<span>
Step 1: </span><span>−(−k)−1(−86)+10=−4
Step 2: </span><span>k−1(−86)+10=−4
Step 3: </span><span>k+86+10=−4
Step 4: </span><span>k+96=−4
Step 5: </span><span>k=−96−4
Step 6: </span><span>Subtract </span>4<span> from </span><span>−96</span><span> to get </span><span><span><span>−100</span>.</span></span>
Lets call those two unknown numbers a, b and write the info in the problem as equations:
a*b = 30
a + b = 40
lets solve for a in the second equation and substitute in the first:
<span>a + b = 40
</span>a = 40 - b
therefore:
<span>a*b = 30
</span>(40 - b)b = 30
40b - b^2 = 30
b^2 - 40b + 30 = 0
if we apply the general quadratic equation to solve we have:
b = (40 +- √(1600 - 120))/2
b = (40 +- √(1480<span>))/2
</span>b = (40 +- 38.47)/2
There are two solutions:
<span>b1 = (40 + 38.47)/2
</span><span>b1 = 39.24
b2 = (40 - 38.47)/2
</span>b2 = 0.765
lets use the second solution <span>b2 = 0.765, and substitute in the first equation to find a:
</span><span>a*b = 30
</span>a*0.765 = 30
a = 30/0.765
a = 39.216
so the numbers are 39.216 and 0.765
2 ab squared + -5 ab squared = 2-5 = -3 ab squared.
Therefore -6 ab squared + x must be -3 ab squared so x is 3 ab squared
