Pulling out a black pen first will grant you a 40% chance of that occurring, then when you put it back the probability of you pulling out a red pen would be 50% so in decimal form these two values would be .40 and .50 multiply these two together you should get .20 or a 20% chance. Also a written fraction would be 1/5, all of which are valid answers.

Answer:
54 ~ see below for explanation
Step-by-step explanation:
you're going to replace n with the 6 since n= 6
so (8+3)6
then you're going to add 8+3 in the parenthesis because of PEMDAS
(9)6
you're going to multiply 6 by 9 since 9 is in parenthesis (a number in parenthesis means multiply)
then you get 54 so the answer would be 54.
The first one is the answer
