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.
