What is the chance of rolling a 4 with a single die three times in a row

Answers

Answer 1

Answer:
The key thing to remember when you're working a problem like this is that
the cube has no memory ... it doesn't know what happened on the last roll,
so the chance of any particular thing happening on the 2nd roll, or on the
100th roll, is the same as it was on the first roll.

Probability of success = (number of ways to succeed) / (total possibilities)

Number of ways for a 4 to come up . . 1
Total possible results of the roll . . . . . 6

Probability of rolling a 4 . . . . . 1 / 6 .

Probability of rolling two 4s . . . (1/6) x (1/6)

Probability of rolling three 4s . . (1/6) x (1/6) x (1/6) = 1/216 = about 0.46% .

Answer 2

Answer: The probability of rolling 4 in one roll is $(1)/(6)$ .
So the probability of rolling 4 three times in a row is $(1)/(6)\cdot(1)/(6)\cdot(1)/(6)=(1)/(216)$

Answer:

The answer is x=-17/3

Step-by-step explanation:

The Steps:

-8 + 5(1 + x) = 2x - 20

-8 + 5 + 5x = 2x - 20

-3 + 5x = 2x - 20

-3 + 3x = -20

3x = -17

x = -17/3

What is the height of a triangular plate if its area is 1225 square centimeters and the length of its base is 35 centimeters, and how can you calculate this height using the formula for the area of a triangle?

Answers

Answer:

height = 70 cm

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = $(1)/(2)$ bh ( b is the base and h the height )

given b = 35 and A = 1225 , then

1225 = $(1)/(2)$ × 35 × h

1225 = 17.5h ( divide both sides by 17.5 )

$(1225)/(17.5)$ = $(17.5)/(17.5)$ h , that is

70 = h

then the height of the triangle is 70 cm
