Question 1024471: Chris rolls two number cubes, one after another. What is the experimental probability that both number cubes will show a 1?
Would the experimental probability be 1/36, because 1/6 * 1/6 = 1/36 if there are two number cubes.. there is only 1 on a number cube so it would be 1/6. 6 numbers on a number cube. Is it correct?

Question 1024545: Hi I have to find the values of P_1 and P_2 (where the underscore represents a subscript)
2P_1 -5P_2 = -6
and
-P_1 + 3P_2 = 4
I have tried the following but apparently it is incorrect:
D
for the first one I got the answers P_1 =(5P_2÷2)-3 and P_2 = (2P_1÷5)+(6÷5)
for the second I got P_1 = 3P_2-4 and P_2 = (P_1÷3)+(4÷3)
I don't know what I'm doing wrong
