(-2, 2) multiplied by 2.5 is given by 2.5(-2, 2) = (-5, 5)
while (2, 1) multiplied by 2.5 is given by 2.5(2, 1) = (5, 2.5)
There are 24 possible answers, 6 are correct answers and 18 are incorrect answers. By use of the hypergeometric distribution the probabilities of each possible number of randomly selected correct answers can be found, as follows:
P(0) = 0.1379, P(1) = 0.3819, P(2) = 0.341, P(3) = 0.1213, P(4) = 0.017, P(5) = 0.0008, P(6) = 0.000007.
The expected or mean number of correct answers is found from:
![E(X)=0\times0.1379+1\times0.3819+2\times0.341+3\times0.1213+4\times0.017](https://tex.z-dn.net/?f=E%28X%29%3D0%5Ctimes0.1379%2B1%5Ctimes0.3819%2B2%5Ctimes0.341%2B3%5Ctimes0.1213%2B4%5Ctimes0.017)
![+5\times0.0008+6\times0.000007=1.4998](https://tex.z-dn.net/?f=%2B5%5Ctimes0.0008%2B6%5Ctimes0.000007%3D1.4998)
The answer is: 1.4998
