Question

Бросили монету и игральную кость(кубик).Какова вероятность того,что выпадут "герб" и не более 2х очков.Ответ округлите до сотых.

Answer 1

Вероятность выпадения "герба" P1=1/2, вероятность выпадения не более 2 очков P2=1/6+1/6=1/3. искомая вероятность P=P1*P2=1/2*1/3=1/6≈0,17. Ответ: ≈0,17.

Answer 2

Problem Analysis

To find the probability of getting "heads" on a coin flip and rolling no more than 2 points on a die, we need to consider the possible outcomes and calculate the favorable outcomes.

Coin Flip

When flipping a fair coin, there are two possible outcomes: "heads" or "tails". Since we are interested in the probability of getting "heads", there is only one favorable outcome.

Die Roll

When rolling a fair six-sided die, there are six possible outcomes: 1, 2, 3, 4, 5, or 6. We are interested in the probability of rolling no more than 2 points, which includes the outcomes 1 and 2. There are two favorable outcomes.

Calculation

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes.

Number of favorable outcomes = 1 (coin flip) * 2 (die roll) = 2 Total number of possible outcomes = 2 (coin flip) * 6 (die roll) = 12

Probability = Number of favorable outcomes / Total number of possible outcomes = 2 / 12 = 1/6 ≈ 0.17 (rounded to the nearest hundredth)

Therefore, the probability of getting "heads" on a coin flip and rolling no more than 2 points on a die is approximately 0.17.

Conclusion

The probability of getting "heads" on a coin flip and rolling no more than 2 points on a die is approximately
