The probability of drawing a green marble is 8/20.
there are 20 marbles total and 8 of them are green.
angle 1+ angle 2=180 supplementary angles add up to 180
angle 2=x assign angle a variable
angle 1= 3x-38 find equation for first angle
3x+x-38=180 set both angles added together equal to 180
4x-38=180 combine like terms
4x=218 add 38 to both sides
x=54.5 divide by 4
angle 2= 54.5
angle 2= (3x54.5)-38 plug back in and solve
angle 1= 125.5
Using the probability concept, it is found that the correct statements are given as follows:
- The number of possible outcomes is 8.
- P(vowel) + P(consonant) = 1.
<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>.
In this problem, there are eight letters, two of which are vowels and six of which are consonants.
Hence:
- P(consonant) = 6/8 = 3/4.
- P(vowel) + P(consonant) = 1/4 + 3/4 = 1.
E is one out eight letters, hence the probability is drawing the tile with E written on it is 1/8.

Answer:
Step-by-step explanation:
Scale= length on drawing / actual length
Let the actual length b x
3:10=2/5/x
3/10=2/5x
Cross multiply
15x=20
x=4/3
The actual length is 4/3
