Probability helps us to know the chances of an event occurring. The probability that a randomly selected student is a junior is 0.35.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

The probability that a randomly selected student is a junior will be,

P(Junior) = [(Number of Juniors)\(Number of total students)]

P(Junior) = 35/100 = 0.35

Hence, The probability that a randomly selected student is a junior is 0.35.

Please help me with this math question

Dmitriy789 [7]

Answer:

6cm ; 22cm

Step-by-step explanation:

Given that:

Total Length, AD = 28cm

AB =x cm

BC = (x +5)cm

CD = 2x - 1 cm

4x + 4 = 28

4x = 28 - 4

4x = 24

x = 24 / 4

x = 6cm

The length of BD

BD = BC + CD

BD = (x + 5) + (2x - 1)

x = 6

BD = (6 + 5) + (2(6) - 1)

BD = 11 + (12 - 1)

BD = 11 + 11

BD = 22 cm
