Helena has a set of number cards numbered 1 thru 10. If Helena randomly draws two cards from the deck, what is the probability that she will draw an odd number and then a two?
A. 6/10
B. 5/10
C. 1/9
D. 5/90
Answer:
5/90
Step-by-step explanation:
There are 5 odd numbers out of 10
We can use a fraction 5/10
Then we multiply it by 1/9
Because there is only 1 card numbered two in the 9 cards left.
The probability that Helena will draw an odd number and then a two is given by (D) 5/90.
What is Probability?Probability is the possibility of occurence of an event.
In mathematical words, it is ratio of number of favorable case to the total number of cases.
Probability = (Number of Favorable Cases)/(Number of Total Cases)
Now there are 5 odd numbers and 5 even numbers in 1 ro 10.
So favorable case to choose an odd number from 1 to 10 is 5
So the probability to choose odd number from 10 cards = 5/10
Now after choosing one odd total number of card is 9 and there is 4 odd and 5 even cards.
but there is only one 2 numbered card.
So probability to choose a two from rest 9 cards = 1/9
Hence the required probability to draw an odd number and then a two is = (5/10)*(1/9) = (5*1)/(10*9) = 5/90
Hence correct option is (D).

Let's choose two arbitrary points on the graph.
For example, let these be points with coordinates (1, 5) and (2, 8).
Substitute the coordinates of these points into the above formula and derive the equation of a straight line.
\(\dfrac{x-1}{2-1} =\dfrac{y-5}{8-5}\\\\\dfrac{x-1}{1} =\dfrac{y-5}{3}\\\\3(x-1)=y-5\\3x-3=y-5\\y=3x-3+5\\y=3x+2\)

Answer:
13.14cm²
Step-by-step explanation:
First we find the area of the rectangle, based on the diagram, this rectangle measures 10cm by 1cm, or 10cm².
After that we find the area of the half circles, In this case I'm going to assume the half circles have the same diameter. The diameter in 2cm, and the radius is half of the diameter. Sine you need the radius to find the area of the circle we will divide the diameter by 2. So 2 ÷ 2 is 1. Then with this radius we will use the formula for the area of a circle, πr².
3.14(1)²
3.14cm²
In most half circles you would divide by two cince this formula calculates the area of a full circle, but two identical half circles is the same as one full circle.
Add the area of the half circles to the area of the rectangle and you get your answer!
10cm²+3.14cm²=
13.14cm²
