When a fish is selected at random from a tank, the probability that it has a green tail is 0.36, the probability that it has red

fins is 0.59, and the probability that it has both a green tail and red fins is 0.21. What is the probability that the selected fish will not have a red fin or a green tail?

Answer: 0.26

Step-by-step explanation:

As per given , we have

P(green tail) = 0.36

P(red fins) = 0.59

P(both a green tail and red fins ) = 0.21

Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )

<em>[P(neither A nor B)= 1- P(either A or B)]</em>

= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))

<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>

= 1- (0.36+0.59-0.21)

= 1-(0.74)

= 0.26

Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26

Loretta has a patio in the shapea trapezoid. The floor of the patio is shown in the sketch below.12 feet5 feetWood PlanksBrick15
beks73 [17]

We can calculate the width of the rectangle patio with pythagorean theorem:

\begin{gathered} \text{Base of triangle=15-12=3} \\ c^2=a^2+b^2 \\ 5^2=3^2+b^2 \\ b=\sqrt[]{25-9} \\ b=\sqrt[]{16} \\ b=4 \end{gathered}

Then, she need to put trim on the edge of the floow of the patio that is wood planks and DOES NOT share and edge with the brick part:

\begin{gathered} T=12+4+12 \\ T=28\text{ feet} \end{gathered}

Loretta need to put 28 feet of trim.
