The probability of pulling a blue marble and the coin landing tails up is 360/2500
<h3>How to determine the probability?</h3>
The tables of values are given as:
Color Times
Blue 18
Green 20
Yellow 12
Heads Tails
20 30
The probability of obtaining a blue marble is:
P(Blue) = 18/50
The probability of landing tails up is:
P(Tail) = 20/50
The required probability is:
P = P(Blue) * P(Tail)
This gives
P = 18/50 * 20/50
Evaluate the product
P = 360/2500
Hence, the probability of pulling a blue marble and the coin landing tails up is 360/2500

Step-by-step explanation:
Given: 
To find: the correct option
Solution:
A binomial polynomial is a polynomial consisting of two terms.
A trinomial polynomial is a polynomial consisting of three terms.
On multiplying a binomial
to itself, a perfect square trinomial
is obtained.
Here, 
So, 
Here,
is a binomial and it is multiplied to
to get a perfect square trinomial 
Subtract the total of the 3 fish she is buying from the amount of money she has:
85 - (12 + 13 + 14) = 85 - 39 = 46
She has $46 to spend on crabs.
Divide the amount she has to spend by the price on one crab:
46 / 8 = 5.75
Since it isn't a whole number you need to round down, since she cant buy 0.75 of a crab.
She has enough money to buy 5 crabs.
