In a certain college, 33% of the math majors belong to ethnic minorities. If 7 students are selected at random from the math maj
Digiron [165]

Answer: a) 0.996, b) 0.253, c) 0.02.

Step-by-step explanation:

Since we have given that

Probability of success = Probability of the math majors belong to ethnic minorities = 33% = 0.33 =p

Probability of failure = q = 1-0.33 = 0.67

Number of students selected = 7

a) No more than 5 belong to an ethnic minority

So, using "binomial distribution", we get that

P(X\leq 5)=\sum^5 _{x=0} ^5C_x(0.33)^x(0.67)^{5-x}=0.996

b. Exactly three of them belong to an ethnic minority

So, it becomes,

P(X=3)=^7C_3(0.33)^3(0.67)^4=0.253

c. None of them belong to an ethnic minority

P(X=0)=^7C_0(0.33)^0(0.67)^7=0.02

Hence, a) 0.996, b) 0.253, c) 0.02.

What is 12 lbs 5oz -7lbs 10oz
ArbitrLikvidat [17]
You can first convert everything to ounces and then subtract, when you get your answer convert it back to lbs.
*16 oz = 1 lb

12 lbs 5 oz = 197 oz
7lbs 10 oz = 94 oz

197 - 94 = 103

103/16
= 4 lbs and 7 oz

hope this helps :)

Anuta_ua [19.1K]

Answer:

60 minutes for the larger hose to fill the swimming pool by itself

Step-by-step explanation:

It is given that,

Working together, it takes two different sized hoses 20 minutes to fill a small swimming pool.

takes 30 minutes for the larger hose to fill the swimming pool by itself

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

<u>To find LCM of 20 and 30</u>

LCM (20, 30) = 60

<u>To find the efficiency </u>

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

x = 60/30 =2

x + y = 60 /20 = 3

Therefore efficiency of y = (x + y) - x =3 - 2 = 1

so, time taken to fill the swimming pool by small hose = 60/1 = 60 minutes
