Question

you pick a card at random. 2 3 4 5 6 7 8 9 what is p(odd)? write your answer as a percentage. %

Explanation:

Step1: Count total number of cards

There are 8 cards in total.

Step2: Count number of odd - numbered cards

The odd - numbered cards are 3, 5, 7, 9. So there are 4 odd - numbered cards.

Step3: Calculate probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, $P(\text{odd})=\frac{4}{8}$.

Step4: Convert to percentage

$\frac{4}{8}=0.5$, and $0.5\times100 = 50\%$.

Answer:

50%
