There are two blue balls and two red balls in a box. At each turn, you will guess the color of the ball you are about to randoml

Blababa [14]

Answer: now, the expected value will be x = p1*0$ + p2*1$

where p1 is te probabilty of a fail and p2 the probability of succes.

Ok, we will have 4 steps here.

1) there are 4 balls, and if we chose a spesific colour, there are 50% chance of succes. x = 0.5$

2) there are 3 balls, but yo know that if in the first step you graved a blue ball, then here you have a 66% of getting a red one, so if you play optimaly, you will guess red. x = 0.6$

3a) now there are two posibilities, in the last step yo get the other blue ball, so now are two red balls in the box, and you have guaranted 2 bucks. x = 2$ (but you failed in the last step)

3b) if in 2 you get a red ball, then again you have a 50/50 chance for each colour. x= 0.5$

4) there's only one ball in the box, you get a dollar x = 1 $

so if you go with the 3b path, te expected value will be 2.6$

with 3a) x = 2.5$

Rewrite the equation 2 x + 3 y = 6 in slope-intercept form<br> I will give brainliest :-)

Vladimir [108]

Step-by-step explanation:

2x + 3y = 6

3y = -2x + 6

divide through by 3

y = (-2/3)x + 6............1

but equation of a straight line is

y = mx + c..............2

compare equation 1&2, m = -2/3 and c = 6

where m = gradient

c = intercept

Given the argument: Oleg is a math major or Oleg is an economics major. If Oleg is a math major, then Oleg is required to take M

Margarita [4]

Answer:

Logic with the use of Truth Table

Step-by-step explanation: a) Oleg is a math major= P; Oleg is a economic major=Q; Oleg is required to take math 362=R; Oleg is not required to take 362=←R

b)i) Oleg is a math major or Oleg is an economic major:

P║ Q ║ P∨Q

T T T

T F T

F T T

F F F

ii) Oleg is a math major, then Oleg is required to take Math 362:

P║ R ║ P∧ R

T T T

T F F

F T F

F F F

iii) Oleg is an economic major or Oleg is not required to take Math 362:

Q║ ←R ║ Q ∨ ←R

T T T

T F T

F T T

F F F

c) It is valid because Oleg can only take Math 362 since Oleg is a math major, therefore, it follows that, R ∧ ( P ∨ Q) is valid.

Please answer ASAP. Thank You.

Usimov [2.4K]

Answer:

$(-\infty,-4]$

Step-by-step explanation:

So we have the inequality:

$x\leq -4$

This means that our solution is all numbers <em>less than or equal to </em>-4. Therefore, in interval notation, this is:

$(-\infty,-4]$

This represents all the numbers from negative infinity up until -4. This is equivalent to the inequality.
