<h2>Answer:</h2>

To estimate the probability that more than 2 out of 7 candy bars will include a coupon, the student must count the number of trials with more than two 1's. and divide by the number of trials.

This gives an estimated probability of about 0.1875.

<h2>Step-by-step explanation:</h2>

1 represent a candy bar with a coupon and numbers 2 through 5 represent a candy bar without a coupon.

Now we are asked to find the probability that, if she buys 7 candy bars, more than 2 will include a coupon.

Total number of outcomes=16

Number of favorable outcomes(i.e. the outcome which have more than 2 one) = 3

( Since the outcomes are: 2113415 4341112 1455141 )

Hence, the probability is the ratio of Number of favorable outcomes to the total number of outcomes.

i.e. $Probability=\dfrac{3}{16}\\\\\\Probability=0.1875$

Consider the enlargement of the pentagon. A small pentagon has a bottom side length of x centimeters and left side length of 7 c

LuckyWell [14K]

When the pentagon is drawn to scale then its value of x will be x=3.3 cm

<h3>What is the pentagon?</h3>

The pentagon is defined as the shape having five sides connected together.

Now it is given in the question that

For small pentagone

Bottom =x

left =7 cm

For larger pentagone

Bottom=7cm

left=15cm

Now since the pentagon is actually dilated from its size to the new bigger size. It means that the equivalent ratio of both the pentagons will be equal.

For smaller pentagon

$\rm Equivalent \ Ratio = \dfrac{Bottom}{Left} =\dfrac{x}{7}$
