Ajar contains ten black buttons and six brown buttons. if 9 buttons are picked at random, what is the probability that exactly five of them are black?

Step-by-step explanation:

It is given that A jar contains ten black buttons and six Brown buttons.

Therefore, total number of buttons= 16.

Then, the probability of getting black button will be= and the probability of getting brown button=.

It is given that 9 buttons are picked at random and We have to find he probability that exactly five of them are black. Since, it is the case of the random variables, therefore the  probability that exactly five of them are black=

=

=

Thus,probability that exactly five of them are black=.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
