Question

Lewis is rolling a 10-sided die 250 times. Each side of the die is labeled with a number 1 – 10. Based on the theoretical probability, how many times would Lewis be expected to roll a multiple of 3? 25 30 75 83

Answer 1

okay so multiples of 3 on a 10 sided die is 3,6,and 9 so 3/10 times
if your rolling it 250 times you cross multiply with x so the equation would be 3/10= x/250
do 3x250 which is 750
750//10 is 75
x=75 so its your answer:)
