第 5 个问题 a multiple choice exam has 10 questions. each question has 3 possible answers, of which one is correct. a student knows

tatuchka [14]

The chances that the student was merely guessing is 1/3.

Bayes Theorem determines the conditional probability of an event A given that event B has already occurred.

denoted by

$P(A/B)=\frac{P(A)*P(B/A)}{P(B)}$

let A be the event that the student knows the answer .

B be the event that the student does not knows the answer .

and

E be the event he gets answer correct .

According to the given question

$P(A)=\frac{4}{10} \\\\ P(B)=1-\frac{4}{10} =\frac{6}{10}$

Probability that the answer is correct ,given that he knows the answer is

$P(E/A)=1$

Probability that the answer is correct ,given that he guesses it is

$P(E/B)=\frac{1}{3}$ [as the MCQ has 3 options and only one is correct]

We need to find the probability that he guesses the answer given that it is correct.

Required probability $P(B/E)=\frac{P(B)*P(E/B)}{P(A)*P(E/A)+P(B)*P(E/B)}$

Substituting the values we get

$P(B/E)=\frac{\frac{6}{10} *\frac{1}{3} }{\frac{4}{10} *1+\frac{6}{10} *\frac{1}{3} }$

$=\frac{6}{30}*\frac{30}{18} \\ \\ =\frac{6}{18} \\ \\ =\frac{1}{3}$

Therefore , the chances that the student was merely guessing is 1/3.

What is the end behavior of the graph of the polynomial function y = 7x^12 – 3x^8 – 9x^4?

Kazeer [188]

The degree of the equation is 12 which means it's even. The leading coefficient is 7 which means it's positive. According to the these, the end behavior of the graph is:

f(x)→+∞, as x→−∞
As x approaches negative infinity, the value of f(x) approached positive infinity

f(x)→+∞, as x→+∞
As x approaches positive infinity, the value of f(x) approached positive infinity

What ordered pairs are solutions for the equation y=-2x+5

Shalnov [3]

Answer:

( 0 , 5 ) , ( 1 , 3 ) ( 2 , 1 )

Step-by-step explanation:

1. x=0

y=-2(0)+5

y=5

( 0 , 5 )

2. x=1

y=-2(1)+5

y=-2+5

y=3

( 1 , 3 )

3. x=2

y=-2(2)+5

y=-4+5

y=1

( 2 , 1 )
