Find the indicated probability.

Ksju [112]

Answer:

$P(B) = 0.55$

Step-by-step explanation:

Given

$P(A\ or\ B) = 0.8$

$P(A) = 0.4$

$P(A\ and\ B) = 0.15$

Required

Find P(B)

In probability, we have:

$P(A\ or\ B) = P(A) + P(B) - P(A\ sd B)$

Substitute values

$0.8 = 0.4 + P(B) - 0.15$

Collect Like Terms

$P(B) = 0.8 - 0.4 + 0.15$

$P(B) = 0.55$

lou thinks the expression 27x^3-64 factors to (3x-4) (9x^2+12x+16). is he correct? How can you check his work? Show all work to

larisa [96]

Answer:

Step-by-step explanation:

(a³ - b³) = (a - b) (a² + ab + b²)

27x³ - 64 = 3³x³ - 4³

= (3x)³ - 4³ {a = 3x & b= 4)

Substitute in the above formula.

= (3x -4)([3x]² + 3x*4 + 4²)

= (3x - 4)(9x² + 12x + 16)

The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).
