Answer:
P(Q or C) = 0.25
Step-by-step explanation:
We are given the following in the question:
Letters:
A, C, Q, U, A, I, N, T, A, N, C, E
Total number of observations, n = 12
We have to find the probability that a randomly selected letter is Q or C.
Formula:
P(Q or C) =
![=\dfrac{\text{n(Q or C)}}{n} = \dfrac{3}{12} =0.25 = 25\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Ctext%7Bn%28Q%20or%20C%29%7D%7D%7Bn%7D%20%3D%20%5Cdfrac%7B3%7D%7B12%7D%20%3D0.25%20%3D%2025%5C%25)
Thus,
P(Q or C) = 0.25
