A family that has two children, both are girls, given that at least one of them is a girl, has probability of 1/2 or 50%.

Probability is the likelihood of an event to occur. The value is from 0 to 1 or from 0% to 100%.

For an experiment having n number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability (Event) = Favorable Outcomes/Total Outcomes = x/n

Given that at least one of the two children is a girl, then we are sure that one must be a girl. The other child will either be a boy or a girl. The possible outcomes could have been:

(G, G) and (G, B)

Probability (Event) = Favorable Outcomes/Total Outcomes = x/n = 1/2 = 50%

Write the percent as a decimal and as a fraction in simplest form 75%

Simora [160]

To change from percent to decimal, move the decimal place to the left two times. In this case the decimal is after the 75. so the decimal is .75 To write .75 as a fraction put 75/100 because it is in the hundredths place. Reduce by dividing both parts by 25. the fraction is 3/4

Hope that helped! if you don't get it ask and ill re explain!

The square pyramid pictured below has a surface area of

Evgen [1.6K]

Answer:

Step-by-step explanation:

Triangles

Area of a triangle = 1/2 b * slanted height

b = 6 m

h = 9 m

Area of 1 triangle = 1/2 * 6 * 9

Area of 1 triangle = 27

Area of all 4 triangles = 4*27 = 108 m^2

==================

Base area

The base is a square. All 4 sides are equal.

The formula for a square is s^2

Area = (6 m)^2

Area = 36 m^2

Total area

Total Area = 108 m^2 + 36 m ^2

Total Area = 144 m^2

Which number produces an irrational number when multipled by 1/4

BabaBlast [244]

Answer: Any irrational number

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction of two integers where the denominator is different from zero, it is also characterized by the fact that its decimal expression is neither exact nor periodic.

As an example of this we have $\pi = 3.141592653 ...$
