What is the probability of rolling 4 even numbers on 4 rolls of a dice

Mathematics
1 answer:
hjlf3 years ago
7 0

Answer:

1/16

Step-by-step explanation:

Possible outcomes when rolling a fair die = 1, 2, 3, 4, 5, 6 (i.e 6 possible outcomes)

Possible outcomes when rolling an even number = 2, 4, 6 (i.e 3 possible outcomes)

Hence P (rolling even number on 1 roll) = 3 / 6 = 1/2

P (Rolling 4 even numbers on 4 rolls) = (1/2)(1/2)(1/2)(1/2) = 1/16

Hazel has an assortment of red, blue, and green balls. The number of red balls is the number of blue balls. The number of green
dem82 [27]

Answer:

Step-by-step explanation:

We are given that Hazel has an assortment of red , blue and green balls.

The number of red balls=The number of red balls

The number of green balls is more than the number of blue balls .

Let number of blue balls=x, Number of red balls=y, Number of green balls =z

Let total number of balls=w

Then number of red balls,y= Number of blue balls=x

According to question

x=y

z>x

The total number of balls,w= sum of all balls

w=x+y+z

w=x+x+z

w=2x+z

substitute x<z

w>2x+x

w>3x

Both side divided by 3 then we get

\frac{w}{3}>x

x.

Hazel will have number of blue  balls is given by the equation

x.

Where x= Number of blue balls

w=Total number of blue balls.

Please help!<br> Thanks<br> BRIANLIEST OF 2 PPL ANSWER
vlada-n [284]

Answer:

PS = 7

k = 9

Step-by-step explanation:

RS = PQ                   Given

3x  - 7 = x - 1            Substitute algebraic terms. Subtract x from both sides

3x-x - 7 = x - 1 - x    Combine

2x - 7 = - 1                Add 7 to both sides.

2x - 7+7 = -1+7         Combine

2x = 6                      Divide by 2

2x/2 = 6/2

x = 3

Length of PS = x - 1 + x + 3x - 7

Length of PS = 5x - 8

Length of PS = 5*3 - 8

Length of PS = 7

=========================

f(x) = k - x^2

x = 2

f(x) = 5  is the given point

5 = k - x^2      Substitute for x^2

5 = k - 2^2      Expand

5 = k - 4          Add 4 to both sides.

5+4=k-4+4      Combine

k = 9
