From the information given:
Random wins 2000 800 400 0
Probabilities 1/10^4 4/10^4 10/10^4 9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92
Answer:
1/38 of Kelly's beads are blue.
Step-by-step explanation:
four eighths = 1/2 or 1 half
1/2 of them are red.
18 white beads, so number of red beads have to be bigger than 18 since she has blue beads too.
So, we can just estimate she has just one blue bead so then the 18 whites become 19 so we need to make red beads the same amount as it is half of the total.
The total is 38 since 19 + 19 = 38 (total beads)
So, blue is 1/38 as a fraction.
Hope this helps. :)

Answer:
Step-by-step explanation:
The standard form of a quadratic is . You need to subtract the x^2 from the right to set the quadratic equal to 0. Then a,b, and c are equal to the values of the coefficients in front of the terms.
