We should each breakdown the probability first for scarves, gloves and hat.
Probability of choosing brown scarf = 1/4
<span>Probability of choosing black gloves = 1/3
</span>There may be no specification of the hat so it is still random, any color of the two hats is possible.
Multiply these probabilities together:
1/4 x 1/3 x 2 = 1/6
The probability of this combination of clothes together is 1/6
The third equation is the correct one. After 100 years, about 115 grams will remain.
Percentage error = 245-230/245 * 100 = 15/245 * 100 = 6.12%
After rounding off, it would be 6%
35,500-27,500= 8000 meaning $8,000 is the profit and the percentage is %35
