you randomly draw a marble out of a bag that contains 20 total marbles. 12 of the marbles in the bag are blue. what is p(draw a blue marble)? if necessary, round your answer to 2 decimal places.

Answer

Explanation:

Step1: Recall probability formula

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

Step2: Identify favorable and total outcomes

The total number of marbles is 20 (total outcomes), and the number of blue marbles is 12 (favorable outcomes).

Step3: Calculate the probability

$P(\text{draw a blue marble})=\frac{12}{20} = 0.60$

Answer:

0.60
