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
