Find the probability that the friend is at least 21 minutes late. is x minutes late. Find the probability that the friend is at least 21 minutes late.

Answer 1

Answer:

0.30

Step-by-step explanation:

Data provided in the question

Uniform density function for a friend = x minutes late

The Friend is at least 21 minutes late

Based on the above information, the probability that the friend is at least 21 minutes late is

$= \frac{Total\ minutes - minimum\ minutes}{Total\ minutes}$

$= \frac{30 - 21}{30}$

= 0.30

Based on the above formula we can easily find out the probability for the friend who is at least 21 minutes late
