An apple tree produces 120 flowers. If the probability of a flower being pollinated successfully is 35%, how many flowers can be expected to develop into fruits? Round to the nearest whole number.
Answer
42
The correct answer is 42 — Thus 42 flowers are expected to become fruits.
Step-by-step solution
- Convert percentage to decimal: 35% = 0.35.
- Multiply number of flowers by probability: 120 × 0.35 = 42.
- Round to the nearest whole number: 42 is already whole.
- Thus 42 flowers are expected to become fruits.
Common mistake: Using 35 instead of 0.35 or mis‑multiplying
Concept tested: Probability in pollination
