The probability of picking a red counter is therefore; 8/25.
<h3>What is the probability of picking a red counter?</h3>
Since the ratio of red to green is 2 :3 and there are 24 green counters, it follows that the number of red counters is;
x = (2/3)× 24 = 16 red.
The total of red and green is; 16 +24 = 40 which constitutes 80% of the total counters.
The total number of counters is therefore; 40/0.8 = 50 counters.
The probability of picking a red counter is therefore; 16/50 = 8/25.

If you need further explanation about how to graph, please let me know.
Hope this helps!! :)
X + y = 5 . . . . . . . . (1)
y = 1/2x + 2 . . . . . .(2)
putting (2) into (1), we have,
x + 1/2x + 2 = 5
3/2x = 5 - 2 = 3
x = (3 x 2)/ 3 = 2
y = 1/2(2) + 2 = 1 + 2 = 3
Answer: the third option.
Actually Welcome to the Concept of the Maths.
Cost of each ticket = £54
Glen purchased tickets= 4
total cost of tickets alone = 54*4 =£216
now calculation of the 5% tax of the tickets,
5/100 * 216 = £ 10.8
hence the total amount Glen has to pay is
=> 216+10.8 = £226.8
Answer: x ~34.31 (rounded)
