Answer: 92
Step-by-step explanation: the probably of getting a score of 4 when rolling a fair six-sided die is 1/6. To estimate the total number of times Charlie will get a score of 4 when he throws the die 550 times, you can use the expected value formula:
Expected Value=(Number of Trials)*(Probably of Success)
Expested Value=550*(1/6)
Expected Value=91.67(rounded to two decimal places)
