The probability of an eclair is 1/15, which means for every 1 eclair there is a total of 15 sweets.
Since the table says there is 3 eclairs, there is 3 x 15 = 45 total sweets.
Now add the 3 different sweets together to equal 45:
3 + 2x+6 + x = 45
Combine like terms:
3x +9 = 45
Subtract 9 from each side:
3x = 36
Divide each side by 3:
X = 36 /3
x = 12
Now you have x, calculate the number of humbugs:
2x +6 = 2(12) +6 = 24 + 6 = 30 total humbugs.
The probability of picking one would be 30/45, which reduces to 2/3.
