Step-by-step explanation:
Answer:
a) P{W>0} = 0.5
b) P{W<0} = 0.5
c) E[W] = 0
Step-by-step explanation:
Solution:
a) P(W > 0) is 0.5 because there is a 0.5 chance the player will win on their first gamble and stop with a net profit.
b) P(W = 0) is 0.25 because there is a 0.5 chance the player will lose on their first gamble, then also a 0.5 chance they will win on their second gamble and stop with a profit of 0.
All other combinations of gambles result in a net loss, so P(W < 0) = 1−P(W > 0)−P(W = 0)
c) The expected value can be obtained by summing the products of each profit and the probability of that profit. In this case, you have 1∗0.5+0∗0.25+(−1)∗0.125+(−2)∗0.0625, etc. So E(W) is the sum to infinity:
= (1 - n) / 2^( n + 1 )
= 0
Answer:
(2,3)
Step-by-step explanation:
Because both equations involve the y-term -4y, elimination by addition/subtraction is a good choice as we solve this system of linear equations.
Multiply the 1st equation by -1, obtaining -x + 4y = 10; then add the 2nd equation to this result:
-x + 4y = 10
2x - 4y = -8
-------------------
x = 2
Next, find y. Substitute 2 for x in the first equation: 2 - 4y = -10. Subtract 2 from both sides, obtaining -4y = -12. Then y = 3.
The solution is (2,3).
170 deggres because 60 plus 130 is 190 then a circle is a total of 360 so just subtract it and boom 170
