Answer:
7/4
Step-by-step explanation:
1/2 x 2 = 1
3/4 + 1 = 7/4 or 1 3/4
Answer:
x² + 6x + 9
x² + 4x + 3
x³ + 8x² + 21x + 18
x + 2
Step-by-step explanation:
Given in the question two functions,
f(x) = x² + 5x + 6
g(x) = x + 3
1) (f+g)(x)
(x² + 5x + 6) + (x + 3)
x² + 5x + x + 6 + 3
x² + 6x + 9
2) (f-g)(x)
(x² + 5x + 6) - (x + 3)
x² + 5x - x + 6 - 3
x² + 4x + 3
3) (f.g)(x)
(x² + 5x + 6) . (x + 3)
x³ + 5x² + 6x + 3x² + 15x + 18
x³ + 8x² + 21x + 18
4) (f/g)(x)
(x² + 5x + 6) / (x + 3)
(x + 2)
-------------------
(x + 3) | (x² + 5x + 6)
x² + 3x
--------------------
2x + 6
2x + 6

Using P(A∪B) = P(A) + P (B) - P(A∩B)
If we apply this in the question
Then P(S∪T) = P(S) + P(T) - P (S∩T)
= 6/11 + 1/10 - P (S∩T)
= 71/110 - P (S∩T)
But events S and T are mutually exclusive events therefore,
P(S∩T) = 0,
Hence P(S∪T) = 71/110
Answer:
Step-by-step explanation:
There are 10 cubes all together.
You want blue and then red with replacement.
Blue
P(B then red) = 3/10 * 4/10 = 12 / 100
12/100 reduces to 3/25
