Given:
Cards labelled 1, 3, 5, 6, 8 and 9.
A card is drawn and not replaced. Then a second card is drawn at random.
To find:
The probability of drawing 2 even numbers.
Solution:
We have,
Even number cards = 6, 8
Odd numbers cards = 1, 3, 5, 9
Total cards = 1, 3, 5, 6, 8 and 9
Number of even cards = 2
Number of total cards = 6
So, the probability of getting an even card in first draw is:
Now,
Number of remaining even cards = 1
Number of remaining cards = 5
So, the probability of getting an even card in second draw is:
The probability of drawing 2 even numbers is:
Therefore, the probability of drawing 2 even numbers is 
. Hence, the correct option is (b).
Answer:
Note that the line has a y-intercept at (0, 2), with slope m=1 m = 1 . Example 6: Find the equation of the line passing through (−1, 3) and (5, 1). Solution: First, find m, the slope. Given two points, use the slope formula
Answer:

I think the mean of variable a is 4
Answer:
1)= 1 kilogram per liter (kg/l) + 8.35 pound per gallon (lb/gal)
2)= 4.4704 meters per seconds
3)= 12in= 1ft ratio is 12:1
4)= 1ft=12in ratio is 1:12
5)= 3ft= 1 yard ratio is 3:1
6)=1 yard = 3ft ratio 1:3
Step-by-step explanation:
12 in = 1 foot
1 yard = 3 feet
1 yard = 36 in
I hope this helps
