Answer:
0.395
Step-by-step explanation:
The computation of the probability that none of the three shoppers purchased electronics is shown below:
So, first we have to determine the number of shoppers without considering the purchase i.e
= Total number of shoppers - electronics
where,
Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics
= 18 + 25 + 40 + 12 - 25
= 95 - 25
= 70
Now the probability is
= 
= 0.395

Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times
Answer:
45
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
3x+5x+4x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
The smallest angle is 3x
3(15) = 45
-11 / 12 is the answer to the question.<span />
