Re: Maths Questions
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?
