Question

Two coins are tossed simultaneously. What is the probability of getting one head and one tail? ¼ ½ ¾ 2/3 Select the correct answer from above options

Answer 1

(b) 1/2 We know that the coin has two sides head (H) and tail (T) So the possible outcomes are Xm. (where x is the number of outcomes when a coin is tossed and m is number of coins) When there are 2 coins ∴ 22= 4 i.e. head and tail ∴ The possible outcomes are HH, HT, TH, TT. Total possible outcomes =4 ∴ Chances of getting 1 head and 1 tail = 2, i.e. HT, TH By using the formula, Probability p () = number of favorable outcomes/ total number of outcomes ∴ Probability of getting 1 head and 1tail p (1H 1T) = number of 1head and 1tail/total number of outcomes =2/4 = ½
