Correct option is C
Given:
Four unbiased coins are tossed.
We need the probability of getting exactly four heads.
Formula used:
Probability = Favorable outcomes / Total outcomes
Solution:
Total outcomes for tossing 4 coins = 24 = 16
Favorable outcomes for 4 heads = 1 (HHHH)
Probability = Favorable outcomes / Total outcomes
=> Probability = 1/16
∴ The correct answer is option (c).
