The letters in the word SANTA CLAUS are printed on identical index cards with one letter per card. The ten cards are then placed in a hat, and one card is randomly chosen (without looking) from the hat. The chance process we are interested in is what letter is on the selected card.

The missing part:

Make a model of probability showing the set of outcome and the probability value of each outcome.

Step-by-step explanation:

From the given information:

a) From the word SANTA CLAUS, outcomes are all distinct letters.

This implies that the outcomes are S, A, N, T, C, L, U, S

For  S, N, T, C, L, U, S letters, each of them is repeated once.

Thus, their respective probability =

A is repeated thrice, so probability for A =

Using the probability distribution table; we have the following.

outcome      S        A        N        T        C        L        U        S
