Answer:

A

500 Heads, 500 Tails

Step-by-step explanation:

A fair coin has tow faces, head and tail.

-The probabilities of the two faces occurring are equal:

[tex]p(h)=p(t)=0.5[/tex]

-In 1000 flips:

[tex]p(h)=p(t)=0.5\\\\\therefore E(h)=E(t)=np=1000\times 0.5=500[/tex]

Hence, the expected number of heads is 500 and of tails is 500.
