It would be 2/6 or 1/3 unless you mean 3 or less which would be 3/6 or 1/2

1/3 because only 1 and 2 is less than 3 out of the 6 numbers. 2/6 = 1/3.

Keith_Richards [23]

For 1 play, the chance of gaining $8 is 4/38, while the chance of losing the $1 is 34/38. Therefore, the expected value is ($8)(4/38) + ($-1)(34/38) = $(-1/19). Over 50 plays, which are mutually independent of each other, we multiply the number of plays by the expected value to get $(-50/19) = $-2.63.

A statement and portions of the flowchart proof of the statement are shown.

Sedaia [141]

In box 1, the reason that justifies the statement, m∠BAD = m∠BAC + m∠CAD, is: angle addition postulate.

<h3>What is the Angle Addition Postulate?</h3>

The angle addition postulate states that the measure of a larger angle equals the sum of smaller angles that make up the larger angle.

∠BAD comprises of ∠BAC and ∠CAD.

Therefore, based on the angle addition postulate, m∠BAD = m∠BAC + m∠CAD.

The missing reason in box 1 would be: angle addition postulate.

vlada-n [284]

Answer:

$\fbox{Volume \: of \: pyramid \: = 24 ft³}$

Step-by-step explanation:

Given:

shape of object = Pyramidal

length of base l= 4ft

width of base w = 3ft

height of pyramid h = 6 ft

To find:

volume of pyramid = ?

Solution:

$Volume \: of \: pyramid= \frac{l \times w \times h}{3} \\ Volume \: of \: pyramid= \frac{6 \times 4 \times 3}{3} \\ Volume \: of \: pyramid= \frac{24 \times \not3}{ \not3} \\ Volume \: of \: pyramid= 24 \: {ft}^{3}$

$\fbox{Volume \: of \: pyramid \: = 24 ft³}$
