Question

Mindie tosses a coin 50 times and gets 32 heads. Adam tosses the same coin 50 times and gets 28 heads. Cam tosses the coin 50 times and gets 21 heads. Jade tosses the coin 50 times and gets 24 heads.Use the result to predict the number of heads in 1,000 tosses.

Answer 1

Ok, so first you know that each number is out of 50, so to find a percentage you double each number: 64,56,42,48. Now find the mean (add all numbers together and divide by the amount of numbers: 64+56+42+48=52.5. This means the average percentage of heads is 52.5. Now you just need to find 52.5% of 1,000. That's 525. So the answer is 525. Your welcome :)
