Answer:
The probability of choosing a yellow marble then choosing another one without replacement is 1/30.
Step-by-step explanation:
First, get the total amount of marbles.
5 + 7 + 4 + 6 + 3 = 25 total marbles.
Now find the probability of finding a yellow marble.
P = 5 yellow marbles / 25 total marbles.
Now find the probability of finding a yellow marble after pulling one without replacement.
P = 4 yellow marbles / 24 total marbles.
To find the probability of both events happening, multiply the probabilities together.
(5/25) * (4/24)
Multiply the numerators and denominators.
20/600
Simplify.
1/30.
Yes it can have equal expressions
Answer: The length of the segment AD = a+b-c
Step-by-step explanation:
Given : Segments AB and CD belong to the same line such that that they overlap.
if length of AB = a units and length of CD = b units
measure of overlapping part = c
Then, the length of the segment AD = length of AB + length of CD - measure of overlapping part
= a+b-c
Hence, the length of the segment AD = a+b-c
