A 12-member jury is to be selected from 15 men and 13 women. Find the probability that this jury has 6 or 7 males.
Bas_tet [7]

Answer:

The right solution is "0.5545".

Step-by-step explanation:

According to the question,

The probability of having 6 or 7 males will be:

= P(6 \ males)+ P(7 \ males)

= \frac{15_C_6\times 13_C_6}{28_C_{12}} + \frac{15_C_7\times 13_C_5}{28_C_{12}}

= \frac{5005\times 1716+6435\times 1287}{30421755}

= \frac{16870425}{30421755}

= 0.5545

A. Sam purchased 3 games for $140 after a discount of 30%. What was the original price?
Semmy [17]

Answer:

a) $175 b) It will be $126

Step-by-step explanation:

Cost price of 3 games= $140

Let the original price of games= $ x

Discount is given= 30%

According to question

x \frac{(100-20)}{100}= $140

x \frac{80}{100}= $140

x ×0.8= $140

x= $ \frac{$140}{0.8}

x= $175

Hence, the original price of games $ 140

(b)  If Sam had given a discount of 20%

Again a discount = 10%

The price of games=$ 140

Now, the selling price will be= 175\frac{(100-20)}{100}×\frac{(100-10)}{100}

Now, the selling price will be= $ 126

Hence, the price will be different.
