Final answer:
To find the probability of picking a ripe orange from the bag, divide the number of ripe oranges (13) by the total number of oranges (20), resulting in a probability of 0.65 or 65%.
Step-by-step explanation:
The probability that an orange picked at random from a bag containing 13 ripe oranges and 7 unripe oranges will be a ripe orange can be calculated by dividing the number of ripe oranges by the total number of oranges. Here's the step-by-step explanation:
- First, calculate the total number of oranges in the bag: 13 ripe + 7 unripe = 20 oranges.
- Next, identify the number of favorable outcomes (picking a ripe orange), which is 13.
- Now, calculate the probability by dividing the number of ripe oranges by the total number of oranges: Probability (ripe orange) = number of ripe oranges / total number of oranges = 13 / 20.
- Therefore, the probability is 0.65, which can also be expressed as 65%.
