Answer:
A. The probability of getting a prize (of either $1200 or $120) if you switch your guess after Montana opens one door is 0.6
B. The fair price you should be willing to pay to play this game is $264
Step-by-step explanation:
A. According ot the given data Let A be the event of wining a prize
Let B the event of losing a prize
P(A)=2/6C1=2/6=1/3
P(B)=1-P(A)=2/3
Hence, after opening the door:
P(A I B)=P(A∩B)/P(A)
P(A∩B)=2/5
P(A I B)=2/5/2/3
P(A I B)=0.6
The probability of getting a prize (of either $1200 or $120) if you switch your guess after Montana opens one door is 0.6
B. The fair price you should be willing to pay to play this game=∑(expected prize) probability
The fair price you should be willing to pay to play this game=1200*1/5 + 120*1/5 + 0*3/5
The fair price you should be willing to pay to play this game=$264
The fair price you should be willing to pay to play this game is $264
Answer:
the correct answer is isosceles
#4
a) 5:1/3 and 1:x
5/ 1/3= 1/x
5x = 1/3
x = 1/3 /5 =1/3 x 1/5 =1/15
x = 1/15 cup of flour to make one roll
b) 3 dozen = 36 1:1/15 and 36:x
1/ 1/15 = 36/x
x =36 x 1/15 = 12/5 = 2 2/5
x = 2 2/5 cups of flour
c) 1:1/15 and x:5 2/3 5 2/3= 17/3
1/ 1/15 = x/ 17/3
1/15x = 17/3
x =17/3 / 1/15
x =17/3 x 15
x =17 x 5
x = 85 rolls
Answer:
y=x+4
Step-by-step explanation:
Slope intercept is y= mx+b
The slope is rise/run or change in y/change in x. Here the slope is 1 since when y goes up1, x goes to the right 1 (1/1=1).
The y intercept is 4 since it hits the y axis at 4.
so it would be y= 1x+4 which is y=x+4
