Answer:

The probability that X is less than 32 minutes is 0.736.

Step-by-step explanation:

Given : The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift. If X has an average value of 24 minutes.

To find : What is the probability that X is less than 32 minutes?

Solution :

If X has an average value of 24 minutes.

i.e. \lambda=24

The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

The exponentially function is \frac{1}{\lambda}e^{-\frac{x}{\lambda}}

The function form according to question is

f(x)=\{\frac{1}{24}e^{-\frac{x}{24}}, x>0\}

The probability that X is less than 32 minutes is

P[x

P[x

P[x

Therefore, the probability that X is less than 32 minutes is 0.736.
