Answer:
10
Step-by-step explanation:
df denote degree of freedom
here in question it is given that eleven different video games showing
so here n=11
we know that for calculation of degree of freedom
we can calculate degree of freedom if the sample size n is given degree of freedom is 1 less than sample space
so degree of freedom = sample size -1 =11-1 =10
so the value of degree of freedom that is df is 10
Answer: 0.5
Step-by-step explanation:
Given
There are 3 blue and 1 yellow marble
The chance of picking two marble out of 3 is 
The total no of ways of picking 2 marbles out of 4 is
