Question
A coin was tossed 1500 times and out of these, 100 times, the coin stuck somewhere so the result was not counted. The frequency of occurrence of a head was 700. Find the probability of occurrence of a tail.
Answer: Option B
:
B
A coin was tossed 1500 times but 100 times result was not counted.
So, the total number of times result counted = 1400
Number of times head comes = 700
Number of times tail comes = 1400 - 700 = 700
Probability of occurrence of tail =Number of times tail comesTotal number of times result counted
Probability of occurrence of tail =7001400
Probability of occurrence of tail = 0.5
