Final answer:
Alyse and Haley should put 7 carrots in the ice chest to have approximately a 40% chance of picking a carrot, based on the chest's capacity of 18 pieces of fruit or vegetables.
Step-by-step explanation:
The student is asking about a probability problem where the ice chest can hold 18 pieces of fruit or vegetables. Alyse and Haley want the probability of picking a carrot to be about 40%. To find out how many carrots they should put in the ice chest, we calculate the number of carrots as a percentage of the total capacity of the ice chest.
We can set up the equation as follows: carrots / 18 = 40/100. When we solve for carrots, we get carrots = 18 * (40/100) = 18 * 0.4 = 7.2. Since we can't have a fraction of a carrot in this context, we'd put either 7 or 8 carrots in the ice chest to achieve approximately a 40% probability of picking a carrot.
The closest whole number to 7.2 is 7, so they should put 7 carrots in the ice chest to get as close as possible to a 40% chance of picking a carrot.
