Answer: 1/2
Step by step explanation:
A coin has two sides. Heads ( H ) and Tails ( T ).
If we toss three coins, then all possible outcomes are:
(H, H, H) , (H, H, T) , (H, T, H) , (T, H, H), (H, T, T), (T, H, T) , (T, T, H) and (T, T, T)
Thus, possible outcomes = 8
Thus, Number of possible outcomes ( atleast 2 heads ) = 4
↪️ (H, H, H) , (H, H, T) , (H, T, H) and (T, H, H).
Thus,
Probability of getting at least 2 heads = Favourable outcomes/ Total possible outcomes
= 4/8
= 1/2
Thus, The probability of getting at least two heads is 1/2.
