What is the probability of rolling a number greater than 4 on a standard six-sided die?

The probability of rolling a number greater than 4 on a standard six-sided die is 2/6 or 1/3. There are 2 outcomes (rolling a 5 or a 6) out of a total of 6 possible outcomes when rolling a die (numbers 1 through 6), so the probability is 2/6 which simplifies to 1/3.

If a jar contains 10 red marbles and 5 blue marbles, what is the probability of randomly selecting a red marble?

The probability of randomly selecting a red marble from the jar is 10 out of the total number of marbles, which is 10 (red) + 5 (blue) = 15. Therefore, the probability of selecting a red marble is 10/15, which simplifies to 2/3 or approximately 0.67.

A bag contains 4 green cards and 6 yellow cards. What is the probability of drawing a yellow card, replacing it, and then drawing another yellow card?

The probability of drawing a yellow card on the first draw is 6/10 or 3/5. Since the card is replaced before the second draw, the probability of drawing a yellow card again on the second draw is also 6/10 or 3/5. Multiplying these probabilities together gives us 9/25 or 36%. Therefore, the probability of drawing a yellow card, replacing it, and then drawing another yellow card is 36%.

A spinner has 8 equal sections, numbered 1 to 8. What is the probability of landing on an even number?

The probability of landing on an even number on the spinner is a total of 4 even numbers out of 8 sections in total, which is a 1/2 or 0.5 chance of landing on an even number.

A box contains 20 identical cards, numbered 1 to 20. If one card is randomly drawn, what is the probability of drawing a multiple of 5?

There are 4 multiples of 5 in the range of numbers on the cards (5, 10, 15, and 20). The total number of cards is 20. Therefore, the probability of drawing a multiple of 5 is 4/20, which simplifies to 1/5 or 0.20, or 20%.

A game has a deck of 52 cards, consisting of 4 suits: hearts, diamonds, clubs, and spades. If one card is drawn at random, what is the probability of drawing a heart?

The probability of drawing a heart from a deck of 52 cards where there are 13 hearts is 13/52, which simplifies to 1/4 or 0.25.

A bag contains 8 red balls, 6 green balls, and 4 blue balls. What is the probability of randomly selecting a blue ball, replacing it, and then randomly selecting a green ball?

The probability of randomly selecting a blue ball followed by a green ball with replacement is calculated by multiplying the individual probabilities. The probability of selecting a blue ball is 4/18 (4 blue balls out of total 18 balls), and the probability of selecting a green ball after replacing the blue ball is 6/18 (6 green balls out of total 18 balls). Therefore, the overall probability is (4/18) * (6/18) = 2/27.

A jar contains 20 purple marbles and 10 orange marbles. What is the probability of randomly selecting an orange marble?

The probability of randomly selecting an orange marble from the jar is \( \frac{10}{30} = \frac{1}{3} \) or approximately 0.33 or 33.3%.

A spinner has 6 equal sections, numbered 1 to 6. What is the probability of landing on a number less than or equal to 3?

The probability of landing on a number less than or equal to 3 on a spinner with 6 equal sections is 3 out of 6, which simplifies to 1 out of 2, or 0.5. Therefore, the probability of landing on a number less than or equal to 3 is 0.5 or 50%.

A box contains 25 identical cards, numbered 1 to 25. If one card is randomly drawn, what is the probability of drawing a prime number?

There are 9 prime numbers from 1 to 25 (2, 3, 5, 7, 11, 13, 17, 19, 23). Therefore, the probability of drawing a prime number from the box is 9/25 or 36%.
