GIVEN:
We are told that all the individual letters of the word WISCONSIN are placed on a piece of paper. Then all nine pieces of paper are placed in a hat.
Required;
Find the probability that a letter chosen at random is a consonant.
Step-by-step solution;
The probability of an event is given by the formula;
![P[event]=\frac{number\text{ }of\text{ }required\text{ }outcomes}{number\text{ }of\text{ }all\text{ }possible\text{ }outcomes}](https://img.qammunity.org/2023/formulas/mathematics/college/6sqgpp0hpso27xxc8uzfhbqwh6zxc9cr1w.png)
The number of all possible outcomes is the total number of letters that stands a chance of being selected, and that is 9. The number of required outcomes for this experiment is 6 (that is, 6 consonants).
Therefore, the probability of selecting a consonant by random is;
![\begin{gathered} P[consonant]=(6)/(9) \\ \\ P[consonant]=(2)/(3) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/i5su3urvs96bk2xgzjfcz3ejz3xia42lh1.png)
ANSWER:
The probability of selecting a consonant is;
![P[consonant]=(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/9z6twp8jh1p0xosbum0tz0phkdmb7hke75.png)
