Answer: a) 1 / ⁴⁰C₅ b) 0.33
Step-by-step explanation:
a) The sample space consists of all numbers 1-40.
Since any of the number can be taken from the sample space so each of five 5 distinct numbers we take has equal probability of occurring. So probability of each 5 numbers set we take will be equal to 1 / ⁴⁰C₅
b)
If we pick exactly 3 even number then that means other 2 will be odd.
So, we have sample space of 40 numbers out of which 20 are even and 20 are odd.
Now we have to pick 3 even out of 20 and 2 odd out of 20.
Probability = ²⁰C₃ * ²⁰C₂ / ⁴⁰C₅
Probability= 0.33
Answer: Row 3
Row 2
6 and 10
Step-by-step explanation: C B A
Answer:
15( b+ a) - 2(a + 0 ) = c
then
c+b = t
We could put the two together to make 15(b+a)- 2(a+0) + b = t
Where t = 8379.70
a= £249.99 b= 329.99
Step-by-step explanation:
Equal amounts are 8549.7 from 30 mowers a+b = small and large.
If we use this as an even and take away a+b at different equations we can find the answer to be 8379.70 on the 2nd equation. First equation = 8579.70
8549.7- 249.99-249.99+329.99 to equal the given year to find c in first equation and total in year = t within the above equation.
