Answer:
I don't think you typed the full problem, but the answer is either that you do the parenthesis first, or that it adds to 10
Step-by-step explanation:
His mom paid 30 and he paid 10 I did 40÷4 the got 10 then times by how many 25% each had
The probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1
<h3>What is probability?</h3>
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total number of marbles = 3+4+2+1 = 10
P(Yellow) = 1/10
P(Blue) = 4/9
Probability of extracting a Yellow marble followed by a Blue marble:
= (1/10)(4/9)
= 4/90
= 2/45
Thus, the probability of extracting a Yellow marble followed by a Blue marble is 2/45 if the bag of 10 Marbles has the following composition: Red – 3 Green – 4 Blue – 2 Yellow – 1

Answer:
20y - 20
Step-by-step explanation:
We multiply the first term and the second term in the parentheses by the 4. That means we do:
4(5y) + 4(-5)
And we simplify to get:
20y - 20
