Question

Samir spins a fair coin and records the results. In the first four spins ‘Heads' comes up each time. Samir says, ‘A head is more likely than a tail'. Is he correct? YES/ NO Give a reason for your answer.

Answer 1

No

Explanation:

A coin has two sides which is the "Head" or the "tail". When a coin is tossed, since it only has two sides, one of either sides can come up because they both have 50-50 chance. The probability of having heads or tails is 0.5 or ½ and either side can come up.

Mathematically,

½ × ½ × ½ × ½ = ¹/₁₆

The probability of getting heads four times in a row when the coin is tossed is ¹/₁₆.
