Question

four coins are tossed simultaneously. find the probability of getting odd umber of tails​

Answer 1

probability of getting odd number of

tails 2/8

Answer 2

Answer:

We have 4 coins, so in each coin we can either get a head or a tail. The possibility of odd tails is given be either 1 tail or 3 tails.

1 tail : 4 ways (4 coins)

3 tails = 1 heads : 4 ways again

So total = 8 ways

Total no of possibilities = (no of possibilities on each coin)^ (no of coins)

= 2^4

= 16

Probability of odd tails = 8/16 = 1/2
