Question

The probability distribution histogram shows the number of days a book is checked out of a library.

What is P(3≤X<12) ?

Answer 1

From the probability distribution histogram for number of days a book is checked out of a library

$\boxed{P(3\le X\le 12)=0.4}$

Step-by-step explanation:

Probability distribution histogram tells us about the probabilities associated with all the possible outcomes of an event

The x axis represents the possible values of X and the y axis represents the probabilities

To find the probability we just need to see the corresponding value from the y-axis

Since the books checked out of a library will be an independent event

Therefore, sum of the probabilities associated with the events from 3 to 12 will give us the desired result.

Thus,

$P(3\le X\le 12)=0.05+0.2+0.15=0.4$
