Attempted by 65 students.
Show answer & explanation
Correct answer: A
Key idea: independent tosses multiply probabilities.
Probability of heads on one toss = 1/2.
For both tosses to be heads, multiply: 1/2 × 1/2 = 1/4
Alternatively, sample space = {HH, HT, TH, TT}; only HH is favorable, so probability = 1/4.
