E(2x+y) is me ex or ey ki values di hoi the.

ek long me Sp ki value find karni the isy 2 parts bny hoy thy .

ek long measurment stages btani the 5 statments di hoi the

baqi mujhe yad nai

overall easy tha but long bht mushkil thy mera time nai menage hoa ...

e ki value zror ya rakhna ..

All objectives were quite easy

here are the most of the questions.....

I dont have full questions...

but I know what you had to find.

2 or 3 questions I did not note

But an equation was given in them

any way the rest are as foloows

to Find bcr

to find Fpc

to find M.D

had to find confidence interval

find joint probability ...a table was also given

find mean and variance (both in one question

Find median

had to test a hypothesis

and had to find margional probability ,.a table was given

Todat sta301 paper

90% mcqs were from moaaz and waqar siddhu files but phr b 20 lectures ek bar lazmi study kren q k mcqs me statement change hoti.

Subjective part

1. Define discrete variable

2. Cumulative frequency nikalni the

3. Mid points nikalnay thy classes k

4. Probablility of cards nikalni the

5. Ek question permutation se tha

Subjective part:

Q1. What are the properties of discrete probability distribution?(2)

Q2. For 10 values, we are given ∑(x-x')=30, FIND mean deviation ,M.D(2)

Q3. If A={a,b,c}; B={d,e,f} and C={a,e,i,o,u}...verify

A U (B U C)= (A U B) U C (5)

Q4. A frequency distribution was given, we had to find "cumulative frequency" (5)

Q5. Differentiate between discrete variable and continuous variable.(3)

mcqs 1) when two coins are tossed then what is the probability that atmost one head appears.

Sol: S = {HH,HT,TH,TT} A = {HT,TH,TT} n(S)= 4, n(A)= 3 P(A)= n(A) / n(S)= 3/4

2) In how many ways can 4books can be arranged on shelf?

3) when two events are independent, P(A)=0.5, P(B)=0.2 then find P(AnB)=? Sol: When two events are independent then P(AnB)=P(A)P(B) put values and get result......
