You can survey a maximum of 333 respondents

Step-by-step explanation:

The total budget available for completing the survey is

$B=1000 \$$

While the cost per respondent in the survey is

$b=3\$$

If we survey $n$ respondent during the survey, then the total cost will be

$cost=nb$

Since the cost cannot be larger than the budget B, then we can write:

$B=nb$

And solving for n,

$n=\frac{B}{b}=\frac{1000}{3}=333.3\sim 333$

So you can survey a maximum of 333 respondents.

If P(A) = 0.3 and P(B) = 0.6 what is P(A or B) if the two events are independent?

Katena32 [7]

Answer:

P(A or B) is 0.72

Step-by-step explanation:

Given : P(A) = 0.3 and P(B) = 0.6

To Find:P(A or B) = P(A∪B)

Solution :

We are given that A and B are two independent events

Property : If A and B are independent events then $P(A \cap B) = P(A) \times P(B)$

So, $P(A \cap B) = P(A) \times P(B)$

$P(A \cap B) =0.3 \times 0.6$

$P(A \cap B) =0.18$

Formula : $P(A \cup B)=P(A)+P(B)-P(A \cap B)$

$P(A \cup B)=0.3+0.6-0.18$

$P(A \cup B)=0.72$

Hence P(A or B) is 0.72

Anarel [89]

I think it's 5. 03? I haven't found the median of anything in a while, so it might be a little inaccurate.

O COUNTING AND PROBABILITY

valina [46]

Answer:

a. $Odds = \frac{3}{7}$

b. $Odds = \frac{7}{3}$

Step-by-step explanation:

Given

$n(Black) = 7$

$n(Grey) = 2$

$n(White) = 1$

$n(Total) = 10$

Solving (a): Odds against winning

Since, the arrow must stop at black, then

The odds against winning is calculated as thus:

$Odds = \frac{n(Total) - n(Black)}{n(Black)}$

$Odds = \frac{10 - 7}{7}$

$Odds = \frac{3}{7}$

Solving (b): Odds in favor of winning

Since, the arrow must stop at black, then

The odds is calculated as thus:

$Odds = \frac{n(Black)}{n(Total) - n(Black)}$

$Odds = \frac{7}{10 - 7}$

$Odds = \frac{7}{3}$
