Final answer:
The number of school lunches that would have carrots if 25 kids have packed lunch is 7.
Step-by-step explanation:
To find the number of school lunches that would have carrots if 25 kids have packed lunch, we can use the probability provided. The probability that a school lunch includes carrots is 3/10, which means that for every 10 lunches, 3 of them will have carrots. Therefore, we can find the number of lunches with carrots by multiplying the probability by the total number of lunches. In this case, the number of lunches is 25, so the number of lunches with carrots would be (3/10) x 25 = 7.
Therefore, the answer is 7.
