Final answer:
The probability P2 is 1.
Step-by-step explanation:
The given question is related to the cumulative distribution function (CDF) of a random variable. The CDF is defined for each value of the random variable and gives the probability that the random variable takes a value less than or equal to that value. In this case, the CDF is given as:
P(A = 0) = 1
P(A = 1) = 1
P(A = 2) = 1
P(A = 3) = 0.56
To find the probability P2, we need to find the probability that A is equal to 2. From the CDF, we can see that P(A = 2) = 1. Therefore, the probability P2 is 1.
