Question

Two coins are thrown at the same time. Find the probability of getting both heads. (A) ¾ (B) ¼ (C) ½ (D) 0

Answer 1

Answer:

If 2 coins are thrown at the same time, then the total outcomes are = 2^2 = 4 (2^2= 2square) . i.e ( HH, HT, TH, TT). Here H = heads and T = tails. If you observe here, (HH) means that on the 2coins thrown simultaneously, both are heads. Here it is only 1 favourable outcome for getting both heads. probability = favourable outcomes/ total outcomes= 1/4. (B) is correct. Hope this helps you.
