Using a fair coin and a number cube with faces numbered 1 through 6, what is the probability of getting heads and rolling a 5?

Mathematics

torisob [31]2 years ago

Step-by-step explanation:

Use Multiplication Principle with states that if a event can occur n ways, and another mutually exclusive event occur p ways, then the total outcome is

n \times p

The possible ways of rolling a dice is 6 and the possible ways of flipping a coin is 2 so we have

6 \times 2 = 12

Now, we use the fact that proabliblity is

Number of favorable outcomes/ Total outcomes.

We can only get a head and a 5 once out of the set so the number of favorable outcomes is 1. Total outcomes is 12 so we have

\frac{1}{12}

A is the answer.

Sveta_85 [38]

Answer:

0.24

Step-by-step explanation:

From the information given:

Let's have a schematic view of a tree diagram

                                                   A

                 P(Santa Cruz)                        P(Isabella)

                  = 13/15                                    = 2/15

P(Success | Santa Cruz) = 0.09              P(Success | Isabella) = x

We are told that many have tried to locate the giant turtle, but 89% of them have failed.

This means the probability of success is:

P(success) = 1 - 0.89 = 0.11

We need to find   P(Success | Isabella),

Suppose   P(Success | Isabella) be x as shown above,

Then:

P (Success) = P(Santa) P((Success | Santa Cruz) +   P(Isabella) P(Success | Isabella)

0.11 = \dfrac{13}{15}(0.09)+ \dfrac{2}{15}(x)

0.11 - \dfrac{13}{15}(0.09)= \dfrac{2}{15}(x)

0.032= 0.133(x)

make x the subject of the formula:

x =  0.032/0.133

x = 0.24

What is the volume of the composite figure shown? (Use 3.14 for π.)
Nimfa-mama [501]
The\ volume\ of\ the\ cone:V_1=\frac{1}{3}\pi r^2 H\\(r-a\ radius;\ H-height)\\------------------\\r=7ft;\ H=7ft\\\\V_1=\frac{1}{3}\pi\cdot7^2\cdot7=\frac{1}{3}\pi\cdot343=\frac{343}{3}\pi\ (ft^2)\\-------------------\\The\ volume\ of\ the\ cylinder:V_2=\pi r^2 H\\(r-a\ radius;\ H-height)\\-------------------\\r=7ft;\ H=6ft\\\\V_2=\pi\cdot7^2\cdot6=294\pi\ (ft^3)\\------------------------\\The\ volume\ of\ the\ composite\ figure: V_F=V_1+V_2

V_F=\frac{343}{3}\pi+294\pi=\frac{343}{3}\pi+\frac{294\cdot3}{3}\pi=\frac{343}{3}\pi+\frac{882}{3}\pi=\boxed{\frac{1225}{3}\pi\ (ft^3)}\\\\\approx\frac{1225}{3}\cdot3.14}=\frac{3846.5}{3}\approx\boxed{1,282.17\ (ft^3)}\leftarrow answer
