<h3>✽ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ✽</h3>

➷ Work out the total number of cards (this will be the denominator for the fraction)

2 + 2 + 14  = 18

Probability of it being a red card: 2/18

Probability of it being a yellow card: 14/18

Add together these probabilities:

2/18 + 14/18 = 16/18

Simplify the fraction:

answer = 8/9

Your probability of a red is 2 out of 18.

Probability of a yellow is 14 out of 18.

Together it is 16 out of 18 or, in simplest form, 8/9.

Hope this is helpful!!

Answer:

A. 12

B. 26

Step-by-step explanation:

A. If the output is x = 3, then we just need to substitute 3 in place of x in the equation 2x + 6. This will give us a new equation, 2(3) + 6. 2 times 3 is 6, so we have 6 + 6 which is 12.

B. If the output is x = 10, then we just need to substitute 10 in place of x in the equation 2x + 6. This will give us a new equation, 2(10) + 6. 2 times 10 is 20, so we have 20 + 6 which is 26.

Write an equation of the line that passes through (2,-3) and is perpendicular to the line y=-2x-3
Alina [70]

Answer:

y = 1/2 x - 4

Step-by-step explanation:

slope of perpendicular line is 1/2

y +3 = 1/2 (x -2)

y + 3 = 1/2x - 1

y = 1/2x - 4

A binomial experiment has 4 trials in which p = 0.4. What is the probability of 3 successes?
Kaylis [27]

The probability of 3 successes is 0.0384

<h3>How to determine the probability?</h3>

The given parameters are:

  • Trials,  n = 4
  • Probability of success, p = 0.4

The binomial probability is represented as:

P(x) = ^nC_x * p^x * (1 - p)^{n-x

So, the probability of three successes is:

P(3) = ^4C_3 * 0.4^3 * (1 - 0.4)^{4 -3

Evaluate the factors in the expression

P(3) = ^4C_3 * 0.0384

Evaluate the combination expression

P(3) = 1 * 0.0384

Evaluate the product

P(3) = 0.0384

Hence, the probability of 3 successes is 0.0384
