Probability that you have chosen 2 red marbles is 3/11
<h2>How to solve?</h2>
Total number of marbles = 6 + 5 = 11
Number of red marbles = 6
Number of blue marbles = 5
Important Points:
1. Replacement is not allowed
2. Blue is followed by Red
Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
Probability of Blue first = 5/11
Probability of Red second = 6/10 (one marble is already taken out)
Probability = 5/11 * 6/10 = 3/11

Answer:
60 degrees
Step-by-step explanation:
Triangles are always equal to 180 degrees. So take the sum of the given numbers and subtract it from 180.
78+42=120
180-120=60 degrees. Hope this helps! :)
Rearrange:
5y = -4x-8 ; solve for y =>
slope intercept form:
y = (-4/5)x-8
thus, the slope is: m = (-4/5)
and the y-intercept = -8
