Question

There are 12 red cards, 17 blue cards, 14 purple cards, and 7 yellow cards in a hat.

Part A. In a trial, a card is drawn from the hat and then replaced 1,500 times. Enter an equation that can be used to predict the number of times a yellow card is drawn, y.

Part B. How many times is a yellow card drawn?

Part C. In the second trial of 1,080 draws, a purple card is drawn 324 times. How much greater is the experimental probability than the theoretical probability?

Answer 2

Answer:

Part A- 7/50 x 1,500 Part B- 210 Part C-2%

Step-by-step explanation:

Part A- To figure out part a, you first need to add all the cards together (12+17+14+7) that will give you 50. Since there are 7 yellow cards, you get 7/50. You have to multiply 7/50 by 1500 because thats the amount of of times it was drawn and then replaced

Part B- Just solve 7/50 x 1500

Part B- You know there are 50 total cards from part A. The experimental probability is 14/50, get that as a decimal, 0.28, multiply that by 100, 28%. Do the same thing for 324/1080 that gives you 0.3 or 30%. Subtract 30 from 28 and you have 2%
