Question

A row of seats in a theater contains 20 seats numbered 101 to 120. What is the probability that a randomly chosen seat in this row will be numbered 104?

a) 1/20
b) 1/15
c) 1/10
d) 1/5

Answer 1

The probability of a randomly chosen seat being numbered 104 in a row of seats is 1/20.

Step-by-step explanation:

Probability is a measure of the likelihood that a particular event will occur. It is expressed as a number between 0 and 1, where 0 indicates that the event will not occur, and 1 indicates that the event will certainly occur. The probability of an event A is denoted by P(A).

The probability that a randomly chosen seat in this row will be numbered 104 can be found by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, there is only one seat numbered 104 out of 20 total seats.

So, the probability is 1/20.
