Question

draw a card from a box filled with numbered cards. cards are returned and shufled after each selection. whats the probability getting a 1 digit value? < 10 = ?%

Explanation:

Step1: Count total number of cards

Count the number of cards in the box. Let's assume there are 20 cards (by counting the visible ones in the image).

Step2: Count number of 1 - digit cards

Count the number of 1 - digit cards (cards with values 1,7,9 etc. which are less than 10). Let's assume there are 12 one - digit cards.

Step3: Calculate probability

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P = \frac{12}{20}\)

Step4: Convert to percentage

\(\frac{12}{20}=\frac{12\times5}{20\times5}=\frac{60}{100} = 60\%\)

Answer:

60%
