Step-by-step explanation:
Given
Let the total probability be 1
Probability that Brian wins a raffle = n/n+2
Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle
Probability that Brian does not win a raffle = 1 - (n/n+2)
Probability that Brian does not win a raffle = 
Probability that Brian does not win a raffle = 
Hence required fraction is
Answer:
130 women
Step-by-step explanation:
First set up a system of equations:
1.23W+2.50M=365.00
W+M=211
Using substitution you get:
1.25W+2.50(211-W)=365.00
Simplify:
-1.25W=-162.5
Divide:
W=130
Evaluate 0.3 y+\dfrac yz0.3y+zy0, point, 3, y, plus, start fraction, y, divided by, z, end fraction when y=10y=10y, equals, 10
nalin [4]
The first thing we must do for this case is to rewrite the expression.
We have then:
0.3y + y / z
We evaluate for y = 10, z = 5:
0.3 (10) + (10) / (5)
3 + 2
5
Answer:
0.3y + y / z
For
y = 10
z = 5
the result is 5.
Answer:
a. Table completed
b. E(X) = -0.5
c. Miguel loses $0.5 each time he plays
Step-by-step explanation:
a. The total outcomes S = {11, 13, 15, 13, 15, 35}
Let A be the event he wins $2 and B be the even he loses $1.
Then, A ={11} and
B = {13, 15, 13, 15, 35}
p(A) = 
p(B) = 
Then, the table would be as follows:
2 -1

b. E(X) = 





c. Based on the result (b), Miguel loses $0.5 each time he plays
