Answer:
0.78
Step-by-step explanation:
We have the next probability distribution:
X P(X)
0 0.2
1 0.3
2 0.5
As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:

The standard deviation is:

Then using the data that we have:

Then the standard deviation is 0.78
Answer:
71
Step-by-step explanation:
1/71 * ? = 1
1/71 * x = 1 [consider 'x']
x = 1/(1/71)
x = (1/1)/(1/71) [1 = (1/1)]
x = (1/1)* (71/1)
x = 71.
