Question

you pick a card at random. 6 7 8 9 what is p(not less than 9)? write your answer as a fraction or whole number.

Explanation:

Step1: Determine total number of outcomes

There are 4 cards, so the total number of possible outcomes is 4.

Step2: Determine favorable outcomes

The numbers not less than 9 among 6, 7, 8, 9 is only 9, so there is 1 favorable outcome.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$, so $P(\text{not less than }9)=\frac{1}{4}$.

Answer:

$\frac{1}{4}$
