4.2 theoretical probability. calculating theoretical probabilities (deck of cards).
if you randomly select a card from a well - shuffled standard deck of 52 cards, what is the probability that the card you select is not a spade?

Explanation:

Step1: Find number of spades

A standard deck has 13 spades.

Step2: Find number of non - spades

There are 52 - 13 = 39 non - spades.

Step3: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$, so $P(\text{not spade})=\frac{39}{52}=\frac{3}{4}$.

Answer:

$\frac{3}{4}$
