you pick a card at random. 2 3 4 5 what is p(prime)? write your answer as a fraction or whole number.
Answer
Explanation:
Step1: Identify prime - numbers
The prime numbers among 2, 3, 4, 5 are 2, 3, 5.
Step2: Calculate probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. The total number of outcomes is 4 (since there are 4 cards). The number of favorable outcomes (prime - numbered cards) is 3. So $P(\text{prime})=\frac{3}{4}$.
Answer:
$\frac{3}{4}$
