Answer:
2.5
Step-by-step explanation:
To find the mean of probability distribution, you need to make a third column on the table which will be the value of the 'x' and P(x) multiplied together. Once you have these values, you add them to find the mean:
x P(x)
0 0.0177 (0*0.0177) = 0
1 0.2433 (1*0.2433) = 0.2433
2 0.2204 (2*0.2204) = 0.4408
3 0.2413 (3*0.2413) = 0.7239
4 0.2773 (4*0.2773) = 1.1092
total: 2.5172
Rounded to the nearest tenth: 2.5
