A drawer contains 3 white shirts, 2 blue shirts, and 5 gray shirts. A shirt is randomly

shutvik [7]

Answer:

Probability that first shirt is white and second shirt is gray if first shirt selected is set aside = $\frac{1}{4}$

Step-by-step explanation:

Given that

3 white, 2 blue and 5 gray shirts are there.

To find:

Probability that first shirt is white and second shirt is gray if first shirt selected is set aside = ?

Solution:

Here, total number of shirts = 3+2+5 = 10

First of all, let us learn about the formula of an event E:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

$P(First\ White) = \dfrac{\text{Number of white shirts}}{\text {Total number of shirts left}}$

$P(First\ White) = \dfrac{3}{10}$

Now, this shirt is set aside.

So, total number of shirts left are 9 now.

$P(First\ White\ and\ second\ gray) = P(First White) \times P(Second\ Gray)\\\Rightarrow P(First\ White\ and\ second\ gray) = P(First White) \times \dfrac{\text{Number of gray shirts}}{\text{Total number of shirts left}}\\\\\Rightarrow P(First\ White\ and\ second\ gray) = \dfrac{3}{10} \times \dfrac{5}{9}\\\Rightarrow P(First\ White\ and\ second\ gray) = \dfrac{1}{2} \times \dfrac{1}{2}\\\Rightarrow P(First\ White\ and\ second\ gray) = \bold{\dfrac{1}{4} }$

So, the answer is:

Probability that first shirt is white and second shirt is gray if first shirt selected is set aside = $\frac{1}{4}$

Austin is serving his child french fries and chicken wings for lunch today. Let be the number of french fries in the lunch, and

seropon [69]

Answer:

25f+100c<500

Step-by-step explanation:

He wants that total calorie count to be less than 500 cals, so we use <.

25f, means for each french fries we have 25 calrs.

100c, for each chicken wings we have 100 calories.

So inequality is 25f+100c<500.

For example, he can not eat 4 french fries and 4 wings (4*25+100*4=500 is not less from 500, it is equal), but he can eat 3 fries and 4 wings (3*25+100*4=475<500).

The sum of three consecutive even numbers is 36. what is the smallest of these numbers?

kap26 [50]

｡☆✼★ ━━━━━━━━━━━━━━ ☾

Call the first even number '2n'

Thus, the next would be 2n + 2

And the next would be 2n + 4

Form an equation:

2n + 2n + 2 + 2n + 4 = 36

Simplify:

6n + 6 = 36

Subtract 6 from both sides:

6n = 30

Divide both sides by 6:

n = 5

2(5) = 10

The smallest number is 10
