Step-by-step explanation:
Flipping two fair coins :
Sample space :
{TH, HT, TT, HH}
Atleast one head = 12
If not = - 24
Probability of atleast one head = 3/4
If not ; probability of 2 tails = 1/4
Hence,
X ______12 ______ -24
P(x) ___0.75 ______0.25
Expected value for of gamble E(x) :
Σx * p(x) = (12 * 0.75) + (-24 * 0.25)
E(x) = 9 - 6
E(x) = 3
Expected value of gamble = $3
I believe it is the second option
Hexagon (try it)
