Two cubes faces are colored with pink and blue colors first cube is painted with 4 faces pink 2 faces

(4/6)*0+(2/6)*1=1/3

So easy,,,,only in case of 0 pink faces you can get probability 1/3

question asked in this elitmus exam logx a+ logx b =? if loga x>=1.solve it
option was 1)0 2)1
11 years agoHelpfull: Yes(4) No(0)
ans is 3.
explanation:
lets say x is the number of pink faces on the second cube.
now
4C1.((x)C1) 1
-------------= -----
6C1.6C1 3
from above equation:
4x/36=1/3
so x=3.
thus 3 faces will be of color pink and 3 will be of blue

probability=possible outcomes/total outcomes
probability=1/3
total outcomes=total no of faces=6*2=12
pink faces in one cube=4
pink face in second cube=x
1/3=(x+4)/12
x=0(on solving)

number of pink color faces in second cube is 0 reason being the probability is 1/3 of same color faces means number of combination is 12..
so we can get the answer if and only if the the all six faces will be colored blue only in that case we can get the desired result as 6x2=12 so the probability will be 12/36=1/3..

Thanks

Two cubes faces are colored with pink and blue colors. first cube is painted with 4 faces pink,2 faces blue. When we throw two dies,the probability of getting same colored face is 1/3. Then find how many faces of second cube is colored with Pink ?
