Question

The numbers 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29 are written on separate cards, and the cards are placed on a table with the numbers facing down.

Answer 1

The probability of picking a card with an even number is $\frac{3}{10}$.

What is probability?

• Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
• The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

To find the probability of picking a card with an even number:

• There are 10 cards on which numbers are written 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29.
• These cards are placed on a table with the numbers facing down.
• To find the probability of picking a card with an even number, first, we count all the even numbers written on the cards.
• 12, 14, and 18 out of 10 cards there are 3 even numbers written on the cards.
• So, the probability of picking a card with an even number is $\frac{3}{10}$.

Therefore, the probability of picking a card with an even number is $\frac{3}{10}$.
