Answer:
A
Step-by-step explanation:
the function is moved up by 8 on the y axis which means you need a +8 that isn't directly attached to the x
Step-by-step explanation:
since the sumation of f(x) of a probability is 1
thw probability to win is o.5 and to lose is o.5 so expected value is xf(x
your expected value will b 0.5 multiply by 5 thats is 2.5 thats your expected gain
