Question:
A coin is tossed 200 times and head appeared 120 times. The probability of getting a head in this experiment is
(a) 2/5
(b) 3/5
(c) 1/5
(d) 4/5
Solution:
(b) 3/5
Probability = Number of times head appeared / Total number of times coin is tossed
= 120/200
= 12/20 … [divide both numerator and denominator by 4]
= 3/5
