The length of a social media interaction is normally distributed with a mean of 3 minutes and a standard deviation of .4 minutes

Kazeer [188]

The probability that an interaction lasts longer than 4 minutes is 0.0062.

<h3>What is probability theory?</h3>

probability theory in mathematics focus on the analysis of random phenomena and this theory let us know that the outcome of a random event cannot be determined before it occurs.

z = (4 - 3)/.4

z = 1/.4

z = 2.5

0.0062

Hence The probability that an interaction lasts longer than 4 minutes is 0.0062.
