Question

ten cards numbered 1 through 10 are mixed together. find the probability of each event. 1. p(7)

Explanation:

Step1: Identify total and favorable outcomes

Total number of cards is $n = 10$. The number of cards with number 7 is $m=1$.

Step2: Use probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(7)=\frac{m}{n}=\frac{1}{10}$.

Answer:

$\frac{1}{10}$
