schepotkina [342]

Yo sup??

To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C

P(A)=0.6

P(C|A)=0.3

P(A and C)=0.6*0.3

=0.18

1) Explain to someone how you would do the problem -12 + 5. Explain to them how they would know if the final answer was going to
nadezda [96]

Answer:

1) -12 + 5 = -7 you just set it up and solve it like a regular problem and then to see if its a - or + we see what number was bigger so -12 is bigger then +5 so our answer is -7

2) 7 -3 + 15 - 2 - 3 + 6 so lets add up all the negative numbers and all the positive numbers so now we have + 28 - 8 so the we solve +28 - 8 = +20 again the sign goes with the bigger number!

Hope this helps!!! Good luck!!! ;)
