Answer:

240/2500

Step-by-step explanation:

A:event of drawing a blue marble from bag

P(A)=number of blue marble/total marbles

      = 12/50

B:event of getting tails on tossing a coin

P(B)=total tails/total tosses

      = 20/50

A∩B:event of getting a blue marble and tails on coin

As we know the two events are independent

Hence, P(A∩B)=P(A)×P(B)

                        =

\dfrac{12}{50}\times \dfrac{20}{50}\\\\\\=\dfrac{240}{2500}

Let x and y be independent each uniformly distributed on {1,2,...,n} find p(x &lt; y )
bulgar [2K]
If we draw the contingency table of x (vertical) against y (horiz.), we have a square.
For n=4, we have   (legend:  < : x<y   = : x=y   > : x>y

y      1  2  3  4
x
1      = <  <  <
2      > =  <  < 
3      >  >  = <
4      >  >  >  =

We see that there are n(n-1)/2 cases of x<y out of n^2.
Therefore, 
p(x<y)=n(n-1)/(2n^2)=(n-1)/(2n)

However, if the sample space is continuous, it will be simply p(x<y)=1/2.

SOLVE CORRECTLY AND SHOW WORKKKK!
nadya68 [22]

Answer:

50=(3x)x

Step-by-step explanation:

50=(3x)x. The question is only asking for the inequality of the problem. Since the area of a rectangle is L x W, you would write L as 3x and W as x, and since the area of the rectangle is given, you can set the area as 50.

The price for 11 ballpoint pens is $11.77. Which of the following represents the same price per pen? A. 4 pens for $4.44 B. 5 pe
Harrizon [31]
First we need to know how much each pen costs.  So we take 11.77 and divide it by 11.  That gives us 1.07 per pen.  So answer choice A has 4 pens for 4.44, so we need to multiply 1.07 x 4.  That gives you 4.28, so we know that isn't the correct answer.  For option B, we need to multiply 1.07 x 5.  That is 5.35, so that also can't be the answer.  For C, we need to do 1.07 x 6, and that gives us 6.42.  So we know the correct answer is option C.
