you pick a card at random. what is p(not 5)? write your answer as a percentage.

Explanation:

Step1: Calculate total number of outcomes

There are 4 cards, so the total number of possible outcomes is 4.

Step2: Calculate number of favorable outcomes

The numbers that are not 5 are 4, 6, 7. So there are 3 favorable outcomes.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not }5)=\frac{3}{4}$.

Step4: Convert to percentage

To convert $\frac{3}{4}$ to a percentage, we do $\frac{3}{4}\times100% = 75%$.

Answer:

75%
