A coin is tossed 3 times. what is the probability of obtaning two heads out of the 3 tosses

Nataly [62]

I answered a similar problem yesterday.
In three coin tosses there are 8 possible outcomes:
H H H
H H T
H T H
T H H
T T H
T H T
H T T
T T T

Of those results, four out of the eight have at least 2 tails and so the probability is (4/8) or50%

If you need the probability of getting EXACTLY 2 tails then the probability is (3/8) or .375

Answer:

Building's shadow length = 180 feet.

Step-by-step explanation:

Given:

A 50-foot flagpole is at the entrance of a building that is 300 feet tall.

Its forms a right angled triangle from both ends,both of them are similar because the angle of the sun is the same at the same time of day.

From similar triangle property we can say that.

⇒ length of the building shadow times height of the flagpole's = length of the flagpole's shadow times height of the building

$\frac{length\ of\ the\ building\ shadow}{height\ of\ the\ building} =\frac{length\of\ the\ flagpole's\ shadow}{height\ of\ the\ flagpole's}$

Plugging the values in the above equation we have,

Let length of the building shadow ='x' feet

⇒ $\frac{x}{300} =\frac{30}{50}$

⇒ $\frac{x}{300}\times 300 =\frac{30}{50}\times 300$

⇒ $x=\frac{300\times 30}{50}$

⇒ $x=\frac{9000}{50}$

⇒ $x=180$ feet.

So the length of the building shadow is 180 feet.

(2³)² solve this problem

max2010maxim [7]

Answer:

$(2^3)^2 = 64$

Step-by-step explanation:

Option 1:

Using the following rule:

$(a^n)^m = a^{nm}$

Put in our expression,

a = 2

n = 3

m = 2

$(a^n)^m = a^{nm}$

$(2^3)^2 = 2^{3*2}=2^6=64$

Option 2:

Using the following rule:

$a^n * a^m = a^{n+m}$

Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.

$(2^3)^2 = 2^3 * 2^3$

If we compare this with $a^n * a^m$ , we can see that

a = 2

n = 3

m = 3 (in this case, n and m are equal)

$a^n*a^m = a^{n+m}$

$2^3*2^3 = 2^{3+3} = 2^6 = 64$

Answer: $(2^3)^2 = 64$
