Question 1110842: Census data are often used to obtain probability distributions for various random variables. Census data for families in a particular state with a combined income of $50,000 or more show that 22% of these families have no children, 24% have one child, 34% have two children, and 20% have three children. From this information, construct the probability distribution for x, where x represents the number of children per family for this income group. (Give your answers correct to two decimal places.)
p(0) children=
p(1) children=
P(2) children=
P(3) children=

Hi
22% of these families have no children, 24% have one child, 34% have two children, and 20% have three children.
22% + 24% + 34% + 20% = 100% (of the children)
p(0) children= .22
p(1) children= .24
P(2) children= .34
P(3) children= .20
