Finding the probability of choosing cards less than five

The video tutorial explains how to find the number of cards with values less than 5 from a set of numbers ranging from 1 to 5. It identifies the numbers 1, 2, 3, and 4 as being less than 5, resulting in four possible choices. The probability of selecting a number less than 5 is calculated as 0.8 or 80%. The discussion also touches on the use of percentages in expressing probabilities.

What is the range of numbers considered in the problem?

• 1 through 6

• 1 through 4

• 1 through 5

• 2 through 5

How many cards have values less than 5?

• 6

• 5

• 4

• 3

What is the probability of selecting a card with a value less than 5?

• 0.9 or 90%

• 0.8 or 80%

• 0.7 or 70%

• 0.6 or 60%

Why is it important to distinguish between 'less than' and 'less than or equal to'?

• All of the above.

• It determines the range of numbers.

• It changes the probability calculation.

• It affects the total number of cards considered.

Why might percentages be used in probability?

• To avoid using fractions.

• To complicate the calculation.

• To confuse the students.

• To make the probability easier to understand.
