What is the experimental probability of rolling a number less than 4?

50%

Step-by-step explanation:

In dice, there are 6 numbers, and less than 4 is 1, 2, or 3. 3/6=50%

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
