Question: A probability function for a discrete random variable, X, is shown below. Fill in the missing probability, P(X=1), to make this a valid probability function.

A probability function for a discrete random variable, X, is shown below.

Fill in the missing probability, P(X=1), to make this a valid probability function.

x	P(X=x)
0	0.1
1	?
2	0.2
3	0.2

Calculate the mean ofX. = ? Find the probabilities below. Give your answers to 1 decimal place (1dp), not as a percentage. P(X<1)= ? P(X2)= ? P(X=0orX=3)= ?
