the experimental probability of an event is based on the results of an experiment that is repeated many times: $p(event)=\frac{number of times desired event occurs}{total number of trials}$. a coin is tossed 40 times. heads appeared 18 times. find the experimental probability of landing on heads.

the experimental probability of an event is based on the results of an experiment that is repeated many times: $p(event)=\frac{number of times desired event occurs}{total number of trials}$. a coin is tossed 40 times. heads appeared 18 times. find the experimental probability of landing on heads.

Answer

Explanation:

Step1: Identify values

The number of times the desired event (heads) occurs is 18, and the total number of trials is 40.

Step2: Apply formula

Using the formula $P(\text{event})=\frac{\text{number of times desired event occurs}}{\text{total number of trials}}$, we substitute the values: $P(\text{heads})=\frac{18}{40}$.

Step3: Simplify fraction

$\frac{18}{40}=\frac{9}{20}= 0.45$

Answer:

$0.45$
