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.

• A. 0.46
• B. 0.5
• C. 0.3
• D. 1

Answer 1

The correct option is B

0.5

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 $=\frac{\text{Number of times tail comes}}{\text{Total number of times result counted}}$

Probability of occurrence of tail $=\frac{700}{1400}$

Probability of occurrence of tail = 0.5
