Eric's class consists of 12 males and 16 females. If 3 students are selected at random, find the probability that they

Reptile [31]

Answer:

The probability that all are male of choosing '3' students

P(E) = 0.067 = 6.71%

Step-by-step explanation:

Let 'M' be the event of selecting males n(M) = 12

Number of ways of choosing 3 students From all males and females

$n(M) = 28C_{3} = \frac{28!}{(28-3)!3!} =\frac{28 X 27 X 26}{3 X 2 X 1 } = 3,276$

Number of ways of choosing 3 students From all males

$n(M) = 12C_{3} = \frac{12!}{(12-3)!3!} =\frac{12 X 11 X 10}{3 X 2 X 1 } =220$

The probability that all are male of choosing '3' students

$P(E) = \frac{n(M)}{n(S)} = \frac{12 C_{3} }{28 C_{3} }$

$P(E) = \frac{12 C_{3} }{28 C_{3} } = \frac{220}{3276}$

P(E) = 0.067 = 6.71%

<u><em>Final answer</em></u>:-

The probability that all are male of choosing '3' students

P(E) = 0.067 = 6.71%

A printer will produce Katie wedding invitations for $210. The price to produce 120 invitations is $290. The printer uses a line

VMariaS [17]

Thank you for asking this question. Here is your answer:

M = y2 - y1/x2 - X1 = M

= 290 - 210/120 - 80

M = 80/40

M = 2

Now we will consider y intercept

y = mx + b

210 = 2(80) + b

210 = 160 + b

b = 210 - 160

= 50

Now we will combine everything in order to get the answer.

y = 2x + 50

y = 2(60) + 50

y = 120 + 50

y = 170

So the final answer for this question is $170.
