Solution
A coin is tossed 200 times and head appeared 120 times. The probability of getting a head in this experiment is `underlinebb(3/5)`.
Explanation:
Total number of times coin tossed = 120
⇒ Total number of outcomes = 120
Number of times head appears = 200
⇒ Total number of favourable outcomes = 200
Probability = `"Total number of favourable outcomes"/"Total number of outcomes"`
⇒ Probability = `120/200`
⇒ Probability = `3/5`
Hence, the probability of getting a head in this experiment is `3/5`.
