What is the probability of flipping a coin and it landing on heads?

The probability of flipping a coin and it landing on heads is 0.5, or 50%. This is because there are only two possible outcomes when flipping a coin - heads or tails - and they are equally likely to occur.

If you roll a standard six-sided die, what is the probability of rolling a number less than 4?

The probability of rolling a number less than 4 on a standard six-sided die is 3/6 or 1/2, which is equivalent to 50%. This is because there are three outcomes (1, 2, 3) out of the total six possible outcomes that meet the condition of being less than 4.

What is the probability of drawing a red card from a standard deck of playing cards?

The probability of drawing a red card from a standard deck of playing cards (which has 26 red cards out of a total of 52 cards) is 26/52 or 1/2, which simplifies to 0.5 or 50%.

If you have a bag with 10 marbles, 4 of which are blue, what is the probability of randomly selecting a blue marble?

The probability of randomly selecting a blue marble from a bag with 10 marbles, 4 of which are blue, would be 4/10, which simplifies to 2/5 or 0.4 (or 40%).

If you spin a spinner with 6 equal sections numbered 1-6, what is the probability of landing on an odd number?

The probability of landing on an odd number when spinning a spinner with 6 equal sections numbered 1-6 is 3/6 or 1/2. This is because there are a total of 3 odd numbers (1, 3, and 5) out of a total of 6 numbers on the spinner, making the chance of landing on an odd number 50%.

What is the probability of rolling two dice and getting a sum of 7?

The probability of rolling two dice and getting a sum of 7 is 1/6 or approximately 16.67%. This is because there are 6 ways to get a sum of 7 when rolling two dice, out of a total of 36 possible outcomes (6 sides on the first die multiplied by 6 sides on the second die).

If you have a jar with 20 jellybeans, 5 of which are orange, what is the probability of picking an orange jellybean without looking?

The probability of picking an orange jellybean without looking from a jar of 20 jellybeans, with 5 being orange, is 5/20, which simplifies to 1/4 or 25%.

What is the probability of spinning a spinner with 4 equal sections and landing on a multiple of 3?

The probability of landing on a multiple of 3 when spinning a spinner with 4 equal sections is 1 out of 4 sections. Therefore, the probability is 1/4 or 0.25, which is equivalent to 25%.

If you draw a card from a standard deck and put it back before drawing again, what is the probability of drawing a heart both times?

The probability of drawing a heart on the first draw is 13/52 since there are 13 hearts in a standard deck of 52 cards. When the card is then put back in the deck, there are still 13 hearts out of 52 cards, so the probability of drawing a heart on the second draw is also 13/52. To find the probability of both events happening, we multiply the probabilities together: (13/52) * (13/52) = 169/2704 or approximately 6.25%. Thus, the probability of drawing a heart both times is 169/2704 or approximately 6.25%.

What is the probability of flipping a coin three times and getting exactly two heads?

The probability of flipping a coin and getting heads is 1/2, so the probability of getting tails is also 1/2. To calculate the probability of getting exactly two heads in three flips, we use the binomial probability formula which is (n! / (k!(n-k)!) * p^k * q^(n-k), where n is the number of trials (3 flips), k is the number of successful outcomes (2 heads), p is the probability of success on a single trial (1/2 for heads), and q is the probability of failure on a single trial (1/2 for tails). Plugging in the values, we get (3! / (2!(3-2)!) * (1/2)^2 * (1/2)^(3-2) = 3/8. Therefore, the probability of flipping a coin three times and getting exactly two heads is 3/8.
