what is the probability of picking a blue marble and rolling a one? write your answer as a fraction or a whole number. with fractions, use a slash ( / ) to separate the numerator and denominator.
Answer
Explanation:
Step1: Calculate probability of picking blue marble
There are 0 blue marbles out of 9 marbles. So probability $P(\text{blue})=\frac{0}{9} = 0$.
Step2: Calculate probability of rolling a 1
A die has 6 sides. Probability of rolling a 1 is $P(1)=\frac{1}{6}$.
Step3: Use multiplication rule for independent - events
Since picking a marble and rolling a die are independent events, $P(\text{blue and }1)=P(\text{blue})\times P(1)$. Substitute the values: $0\times\frac{1}{6}=0$.
Answer:
