Make a Probability Distribution for the Given Set of Events

Make a probability distribution for the given set of events.
-The following table displays a frequency distribution of the number of siblings for students at one middle school. Make a probability distribution for number of siblings. $\begin{array}{r|rrrrrrrr}\text { Number of siblings } & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\\hline \text { Frequency } & 188 & 257 & 135 & 54 & 22 & 8 & 6 & 3\end{array}$

A)
$\begin{array}{r|r}\text { Siblings } & \text { Probability } \\\hline 0 & 0.125 \\1 & 0.125 \\2 & 0.125 \\3 & 0.125 \\4 & 0.125 \\5 & 0.125 \\6 & 0.125 \\7 & 0.125\end{array}$
B)
$\begin{array}{r|r}\text { Siblings } & \text { Probability } \\\hline 1 & 0.530 \\2 & 0.278 \\3 & 0.111 \\4 & 0.045 \\5 & 0.016 \\6 & 0.012 \\7 & 0.006\end{array}$
C)
$\begin{array}{r|r}\text { Siblings } & \text { Probability } \\\hline 0 & 0.279 \\1 & 0.382 \\2 & 0.201 \\3 & 0.080 \\4 & 0.033 \\5 & 0.012 \\6 & 0.009 \\7 & 0.004\end{array}$
D)
$\begin{array}{r|r}\text { Siblings } & \text { Probability } \\\hline 0 & 0.294 \\1 & 0.367 \\2 & 0.212 \\3 & 0.068 \\4 & 0.033 \\5 & 0.012 \\6 & 0.009 \\7 & 0.004\end{array}$
