Answer: 3-4log₃(x)
Step-by-step explanation:
the biggest error
if it is a division of log we have to subtract
log₃(27)-lox₃(x^4)=3-4log₃(x)
The correct question is;
Ellen has a bag with 3 red marbles and 2 blue marbles in it. she is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. what is the best prediction for the number of times that ellen will draw a blue marble?
Answer:
120 times
Step-by-step explanation:
We are given;
Red Marbles = 3
Blue Marbles = 2
Thus;
Total Marbles = 3 + 2 = 5
Probability of of Blue Marbles;
P(B) = 2/5
Total number of Draws = 300
Hence, best prediction for the number of times that ellen will draw a blue marble = 300 x (2/5)
= 120
Thus, prediction is 120 Times that Ellen will Draw Blue Marbles
