a box contains ten cards labeled q, r, s, t, u, v, w, x, y, and z. one card will be randomly chosen. what is the probability of choosing a letter from q to t? write your answer as a fraction.
Answer
Explanation:
Step1: Count favorable outcomes
The letters from $Q$ to $T$ are $Q$, $R$, $S$, $T$, so there are 4 favorable outcomes.
Step2: Count total outcomes
There are 10 cards in total, so total outcomes = 10.
Step3: Calculate probability
Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}=\frac{4}{10}=\frac{2}{5}$
Answer:
$\frac{2}{5}$
