Question

A coin is tossed $80$ times and $45$ of those times it lands heads up. What is the experimental probability of flipping a head in the next toss?

• A. $\frac{7}{16}$
• B. $\frac{9}{16}$
• C. $\frac{5}{16}$
• D. None of the above

Answer 1

The correct option is B $\frac{9}{16}$

Given:
Total number of trials= $80$
Number of times head comes up= $45$

$\text{To find:}$ Experimental probability of flipping a head in the next toss

From the given experimental data, we can find the probability of flipping a head as
$\text{P (H)}=\frac{\text{Number of times head comes up}}{\text{Total number of trials}}$
$\Rightarrow \text{P (H)}=\frac{45}{80}=\frac{9}{16}$

$\therefore$ The probability of flipping a head in ${81}^{\text{st}}$ toss is $\frac{9}{16}$.
