Question

A coin tossed $100$ times. The no. of times head comes up is $54$.What is the probability of tail coming up?

• A. $0.54$
• B. $0.46$
• C. $0.64$
• D. $0.45$

Answer 1

The correct option is B $0.46$

Number of times coin is tossed $=100$

Number of times head come up $=54$

Therefore, Number of times tail come up $=100-54=46$

Probability of head coming up $=\frac{54}{100}=0.54$

Therefore, probability of tail coming up $1-\frac{54}{100}=\frac{46}{100}=0.46$.
Hence, the probability of tail coming up is $0.46$.
