Calculating the Probability of Drawing a Pear or a Plum from the Basket

To calculate the probability of drawing a pear or a plum from the basket, we need to know the total number of fruits in the basket and the number of pears and plums specifically.

According to the information provided, the basket contains: - 3 apples - 5 pears - 7 plums

To find the probability of drawing a pear or a plum, we need to calculate the ratio of the number of pears and plums to the total number of fruits in the basket.

The total number of fruits in the basket is: 3 (apples) + 5 (pears) + 7 (plums) = 15 fruits

The number of pears and plums is: 5 (pears) + 7 (plums) = 12 fruits

Therefore, the probability of drawing a pear or a plum from the basket can be calculated as: (number of pears and plums) / (total number of fruits) = 12 / 15

Simplifying the fraction, we get: 12 / 15 = 4 / 5

So, the probability of drawing a pear or a plum from the basket is 4/5.
