The graph shows a probability distribution. what is p(2.5≤x≤4)?

P(2.5≤X≤4) = 0,3125‬

Step-by-step explanation:

We know that the area under the curve of ANY probability distribution should not be greater than 1.

In this case, we now that 4P = 1, therefore, P=1/4. Where 'P' represents the height of the rectangle that represents the probability distribution.

The probability of P(2.5≤X≤4) will be given by the area of the following rectangle:

(4 - 2.5) × 1,5 = 0,3125‬

Therefore, P(2.5≤X≤4) = 0,3125‬
