VMariaS [17]

The probability that exactly 2 voters will be in favor of the ballot initiative is 0.309.

<h2>Given</h2>

Number of voters who support ballot initiative = 30 % = 0.30

Number of voters who does not support this initiative = 1 - 0.30 = 0.70

Number of voters selected for Surveying = 5

<h3>What is probability?</h3>

The probability of success and failure remain the same throughout the trials.

The probability that exactly 2 voters will be in favor of the ballot initiative is given by;

If P denotes Success and Q denotes failure;

\rm = ^{5}C_2 \times (0.3)^2 \times (0.70)^3\\\\= 10 \times 0.09 \times 0.343\\\\= 0.309

Hence, the probability that exactly 2 voters will be in favor of the ballot initiative is 0.309.

NemiM [27]

\frac{1}{6} or 0.167 pounds more butter was used than sugar

<em><u>Solution:</u></em>

Given that, Desmond's Desserts made a batch of fresh scones with 2/3 of a pound of butter and 1/2 of a  pound of sugar

<em><u>To find: Amount of butter used than sugar</u></em>

From given information,

\text{Butter used} = \frac{2}{3} \text{ pound }

\text{Sugar used } = \frac{1}{2} \text{ pound }

To find how much butter is used than sugar, find the difference between them

Difference = Butter\ used - Sugar\ used

Difference = \frac{2}{3} - \frac{1}{2}\\\\Difference = \frac{2 \times 2-1 \times 3}{3 \times 2}\\\\Difference =\frac{4-3}{6}\\\\Difference =\frac{1}{6} = 0.167\\\\

Thus \frac{1}{6} or 0.167 pounds more butter was used than sugar
