The probability that a person goes to the movies at least 2 times a month is 0.682. Hence option C is the right option.
What do we mean by the probability of an event?
The possibility or chance of an event occurring is intuitively recognized as the probability of it occurring. In the most basic circumstances, the probability of a certain event A occurring as a result of an experiment is calculated by dividing the number of ways that A may occur by the total number of possible outcomes.
The summation of all probabilities regarding a set of events is 1.
How do we solve the given question?
We are given a frequency table showing the number of movies per month and the number of moviegoers.
We are asked to find the probability that a person goes to the movies at least 2 times a month.
The probability that a person goes to the movies at least 2 times a month = Frequency of people going to movies more than or equal to 2 times a month/Total frequency
= (90 + 145 + 235)/690 = 470/689 = 0.68214804063
Rounding this to the nearest thousandth, we get
The probability that a person goes to the movies at least 2 times a month = 0.682.
∴ The probability that a person goes to the movies at least 2 times a month is 0.682. Hence option C is the right option.
