Help Please!

We say that there is an even chance of getting head when a coin is thrown. Which one of the following statements is definitely true?

A There is an even chance that England will win the next football World Cup.
B There is an even chance that I get one head and one tail when I toss a coin twice.
C There is a greater than even chance that I get a 5 when I roll a single dice.
D There is a less than even chance of picking a blue ball from a bag containing 3 blue and 2 red balls

A: incorrect, winning and losing are not equally likely
B: equally likely outcomes when spinning two coins are HH, HT, TH, TT - so even chance of one head and one tail
C: all outcomes on an unbiased die are equal so this is incorrect
D: 5 bals so prob of blue is 3/5 so the statement is incorrect
E: it is certain than a baby will be born somewhere in the next minuts so statement incorrect.

Seems a weird question; where is it from?
