Answer:
3.9
Step-by-step explanation:
Given the data:
Payout ($) (x) : 0 2 4 8 10
Probability p(x) : 0.35 0.2 0.1 0.2 0.15
The expected winning ; E(X) = Σ(x * p(x))
Σ(x * p(x)) = (0*0.35)+(2*0.2)+(4*0.1)+(8*0.2)+(10*0.15)
= 0 + 0.4 + 0.4 + 1.6 + 1.5
= 3.9
Answer:
18.75=p
s=14.06
b=2.34
Step-by-step explanation:
37.75=b+s+p
-4
33.75=b+s+p
s=3/4p
b=1/6s
33.75=1/6(3/4p)+3/4p+p
33.75=3/20p+3/4p+p
(33.75=18/20p+p)20
675=18p+p)/18
37.50=2p)/2
18.75=p
s=3/4p
3/4(18.75)
s=14.06
b=1/6s
1/6(14.06)
b=2.34
37.75-4=18.75+14.06+2.34=35.15
im missing 50 cents somewhere its wrong but close i think sorry
