Calculating Probability

Feedback: Not quite! There are 3 red balls out of 5 total balls. So, the probability of drawing a red ball is $\frac{3}{5}$ or 60%.

Feedback: Not quite! There are 9 blue balls out of 12, so the probability of drawing a blue ball is $\frac{9}{12}$, which simplifies to $\frac{3}{4}$ or 75%.

Feedback: Not quite! The total number of marbles is $6+8+10=24$. The probability of drawing a green marble is the number of green marbles ($8$) divided by the total number of marbles ($24$). So, the probability is $\frac{8}{24}$. This simplifies to $\frac{1}{3}$.

Feedback: Not quite! There are two numbers greater than 4 on a six-sided die: 5 and 6. Therefore, the probability is $\frac{2}{6}$, which simplifies to $\frac{1}{3}$.

Feedback: Not quite! The experimental probability of drawing a red marble is $\frac{150}{500}$ because there are 150 red marbles out of 500 total draws. To simplify, divide both the numerator (150) and denominator (500) by 50. This gives you $\frac{3}{10}$.

Feedback: Not quite! The outcome of flipping a fair coin 10 times is random, so there is no guarantee that exactly half of the flips will be heads and half tails. While it's likely to be close, other outcomes are possible.
