Question

you pick a card at random. what is p(not greater than 4)?

Explanation:

Step1: Determine total number of cards

There are 4 cards in total.

Step2: Determine number of cards not greater than 4

There is 1 card (the card with number 4) that is not greater than 4.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not greater than }4)=\frac{1}{4}$.

Answer:

$\frac{1}{4}$
