you pick a card at random. 3 4 5 what is p(not 5)? write your answer as a fraction or whole number.

Explanation:

Step1: Determine total number of outcomes

There are 3 cards, so total number of outcomes $n = 3$.

Step2: Determine number of favorable outcomes

The numbers that are not 5 are 3 and 4, so number of favorable outcomes $m=2$.

Step3: Calculate probability

The probability formula is $P(A)=\frac{m}{n}$. So $P(\text{not }5)=\frac{2}{3}$.

Answer:

$\frac{2}{3}$
