black is 60% chance, red is 40%?

Question

what is the chance percentage in succesion black in first two draw.

Answer 1

If you mean what I think you do the answer to .6^2 or .36 (Independant probabilities can be multiplied)

Answer 2

if your problem is the same as if you had 100 marbles, and 60 were black and 40 were red, and you were drawing randomly and returning the marbles after they were drawn then,

the chance of drawing two black in succession would be:

.6*.6=.36 (or just over 1 chance in 3)

They see you as clever, gifted, or talented, but modest. Not a person who makes friends too quickly or easily, but someone who's extremely loyal to friends you do make and who expect the same loyalty in return. Those who really get to know you realize it takes a lot to shake your trust in your friends, but equally that it takes you a long time to get over if that trust is ever broken. lol i guess its a little like me

Answer 4

your question is too vague.

if it is a question on marbles as one of the answers stated and you put back the first marble before drawing the second then:
no of black marbles = 60
no of red marbles = 40

chance of getting black marble on first try = 60/100 = 0.6

then you put this black marble back. so the number of black marble is still 60 and the total number still remains 100.

chance of getting black marble on second try is still = 60/100 = 0.6

so you multiply the two: 0.6 x 0.6 = 0.36 = 36%



if however you do not put the first black marble back then the probability will change:

chance of getting black marble on first try = 60/100 = 0.6

since you didn't put the black marble back there is now only 59 black marbles and 99 marbles in all.

chance of getting black marble on second try = 59/99.

so the probability now would be:
59/99 x 0.6 = 0.3576 = 35.76%

You see how the probability changes?
So you really need to be clear on whether you put the marbles back or not.
But i hope this helped anyway! : )

Answer 5

Answer 6

Black is 60% and red is 40%

Answer 7

It may be either two red or two black or one red & one black as well as one black & one Red.
Hence probability is one forth only. In percentage 25% only.

The other way: probability of first ball being black is 60/100. The second ball being black shall be 59/100. So combindly in succession %age of two black ball will be 100* 0.6 *0.59=35.4.

Answer 8

multiply 60% * 60% to get 36%

Answer 9

100 %

Answer 10

Uh...one in 60.
