Given:
The number of times coin flipped is N = 60.
The number of heads is n(H) = 42.
The number of tails is n(T) = 18.
The objective is to find the theoretical probability of coin landing heads up.
Explanation:
The general probability of coin landing heads is,
[tex]P(H)=\frac{n(H)}{N}\text{ . . . . . .(1)}[/tex]On plugging the given values in equation (1),
[tex]P(H)=\frac{42}{60}=0.7[/tex]To obtain the percentage of probability,
[tex]\begin{gathered} P(H)=0.7\times100 \\ =70\text{ \%} \end{gathered}[/tex]Hence, the probability of the coin landing heads up is 70%.
