Answer 1

Okay, so what are the possible outcomes?
i could get a Head and a Tail = HT
a tail and a head = TH
both tails = TT
and, both head = HH

So I have 4 possible outcomes right?

you toss 2 coins that means that your chances are doubled

Answer 4

Answer 5

3... am I right?

Answer 6

@wangkan07 no not really tossing a 2 coins doesn't necessarily double your chances always.

@darkzii yes 3! so, I got 4 possible outcomes, out of which 3 are favorable - so what's the probability?
