Answer:
0.250
Step-by-step explanation:
Given from the question, we know that the summation (adding all values together) of all P(x) values is equal to 1.
And, we do know that P(2) = P(4).
This means , we will subtract all the known P(x) values from 1 to get the value of P(2) + P(4).
P(2) + P(4) = 1 - 0.0425 - 0.3750 - 0.0625 - 0.0200 = 0.500
Since P(2) = P(4), we divide 0.500 by 2 to get the value of P(2) and P(4).
P(2) = P(4) = 0.500 ÷ 2 = 0.250
