irina [24]

Using it's concept, it is found that the experimental probability that the first vehicle rented today will be a pickup truck is of 0.5 = 50%.

<h3>What is a probability?</h3>

A probability is given by the<u> number of desired outcomes divided by the number of total outcomes</u>. For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, we have that out of 4 vehicles, 2 are pickup trucks, hence the experimental probability is given by:

p = 2/4 = 1/2 = 0.5.

Write the expression as a product:<br><br> 1–(2x–1)^2

postnew [5]

Answer:

$1- ( { 2 x - 1)}^{2} = 4x (1 - x )$

Step-by-step explanation:

We want to to rewrite

$1 - ( { 2 x - 1)}^{2}$

Use difference of two squares to get:

${a}^{2} - {b}^{2} = (a + b)(a - b)$

This implies that:

${1}^{2} - ( { 2 x - 1)}^{2} = (1 +( 2x - 1))(1 - (2x - 1))$

${1}^{2} - ( { 2 x - 1)}^{2} = (1 + 2x - 1)(1 - 2x + 1)$

This finally simplifies to:

${1}^{2} - ( { 2 x - 1)}^{2} = 2x (2 - 2x )$

Therefore the required product is

$2x (2 - 2x ) = 4x(1 - x)$

A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting i

dedylja [7]

Answer: C. $\dfrac{1}{3}$

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = $\dfrac{\text{favorable outcomes}}{\text{total outcomes}}$

Probability of selecting a purple ball (second pick)= $\dfrac{4}{12}$

$=\dfrac{1}{3}$

The required probability $=\dfrac{1}{3}$ , so C is correct option.
