Answer:

2 answers.

Step-by-step explanation:

ANSWER 1: With Repetition

Numbers: 1,2,4,5,7,8

There are 4 digits __ __ __ __

1st digit can be filled by any of the 6 numbers.

Similarly 2nd, 3rd and 4th digits.

Hence each digit will have 6 possibilities.

Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296

ANSWER 2: Without Repetition

4 digits __ __ __ __

Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities

The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.

Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.

Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360

Answer:

y = 3/4 + 3/2

Step-by-step explanation:

PLEASE HELP WILL GIVE BRAINLIEST
OlgaM077 [116]

Answer:

G

Step-by-step explanation:

"Any particular event either (a) will happen or (b) won't happen."

That statement above is a certainty, probability = 100% = 1

This means the probability that event E <u>will </u>happen plus the probability that even E <u>won't </u>happen must add up to 100% = 1

So we can always say -->  prob(E) + prob (not E) = 1

The probability you will roll a 5 on a fair, six-sided die is 1/6.

So we use that to find the probability of not rolling the 5.

1/6 + prob(not E) = 1

   prob(not E) = 1 - 1/6  <---- This is answer G

    prob(not E) = 5/6

Hope this helps.

Given s(x) = 2x - 3 and t(x) = 5x + 4. find the formula and domain for s(x) over t(x) and w(x) = t(x) over s(x)
attashe74 [19]
V(x) = (2x - 3)/(5x + 4)   The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.{x | x ∈ R, x ≠ -4/5} w(x) = (5x + 4)/(2x - 3)similarly, x ≠ 3/2so, {x| x ∈ R, x ≠ 3/2}
