Какова вероятность выбора желтого или оранжевого бобов.in English:A bag of jelly beans contains 8 black beans, 10 green beans, 3 yellow beans, and 9 orange beans. What is the probability of selecting either a yellow or an orange bean.​

Answer 1

Вероятность находим по формуле:

а/b, где
а- кол-во благоприятных исходов(желтый или рыжий боб)
b- кол-во всех исходов(все бобы)

Вероятность: (3+9)/(8+10+3+9)= 12/30= 4/10= 0,4

Ответ: 0,4

Answer 2

To find the probability of selecting either a yellow or an orange bean, you need to calculate the ratio of the number of yellow and orange beans to the total number of beans in the bag.

Total number of beans = 8 (black) + 10 (green) + 3 (yellow) + 9 (orange) = 30 beans

Now, let's calculate the probability of selecting a yellow or an orange bean:

Probability = (Number of yellow beans + Number of orange beans) / Total number of beans Probability = (3 yellow beans + 9 orange beans) / 30 beans Probability = (3 + 9) / 30 Probability = 12 / 30

To simplify the fraction, you can reduce it by dividing both the numerator and the denominator by their greatest common divisor, which is 6:

Probability = (12 / 6) / (30 / 6) Probability = 2/5

So, the probability of selecting either a yellow or an orange bean is 2/5 or 40%.
