Answer:
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
