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)

PLEASE ANSWER WITH SOLUTION PLS
katen-ka-za [31]

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].
