A bag contains Blue and Red balls.Two balls are drawn randomly without replacement.the probability of selecting a blue and then a red ball is 0.2..the probability of selecting a Blue ball in the first draw is 0.5,what is the probability of drawing a red ball,given that the first ball drawn was blue..

A.0.4

B.0.2

C.0.1

D.0.5

Whats the distance of C to A,if the distance from A to B=5 and the distance from B to C=3?

HAPY 2018 2 ALL STATISTICIANS ND MATHEMATICIANS IN D BUILDING..ONE LUV.

SOLUTION:If a die is tossed onces,the SAMPLE SPACE=[1,2,3,4,5,6] and the EVEN NO=[2,4,6] Therefore (a)prob of even numba=3/6 can b further simplify as 1/2 and NUMBER LESS THAN 5=[1,2,3,4] (b)the prob of no less than 5=4/6 can b further simplify as 2/3...quietly and easily solved!!!

If a Die is tossed Once,what is the Probability of obtaining (a).An even number (b).A number less than 5..show ur workingz!

Solution to d question:-Y^y+X^x=31 and X+Y=5..LET X=5-Y be equation 1..nd X^x+Y^y=31 be equation 2..Subtitute equa 1 into 2.. (5-y)^(5-y)+Y^y=31..frm equa 1..x+y=5 the val of x and y range from 0

If Y^y+X^x=31 and X+Y=5 Solve simutenously question...Mr Muftau[laplace] nd Edwin[Piosson]

Mathematics and statistics for all,its a web page were we ask and solve applied mathematical and statistical question..2 encourage and developed student in mathematical field..
