Consider the following scenario: Let P(C) = 0.4. Let P(D) = 0.5. Let P(C|D) = 0.6. a. Find P(C AND D). b. Are C and D mutually e
Nataly_w [17]

a. By definition of conditional probability,

P(C | D) = P(C and D) / P(D)  ==>  P(C and D) = 0.3

b. C and D are mutually exclusive if P(C and D) = 0, but this is clearly not the case, so no.

c. C and D are independent if P(C and D) = P(C) P(D). But P(C) P(D) = 0.2 ≠ 0.3, so no.

d. Using the inclusion/exclusion principle, we have

P(C or D) = P(C) + P(D) - P(C and D)  ==>  P(C or D) = 0.6

e. Using the definition of conditional probability again, we have

P(D | C) = P(C and D) / P(C)  ==>  P(D | C) = 0.75

The area of a triangle is 21ft². If the height of the triangle is 7ft, how long is the base of the triangle? Please give your an
tamaranim1 [39]

Answer:

The answer is b = 6

Step-by-step explanation:

Area of a triangle= 1/2 × b × h

A = 21, h = 7, b = ?

21 = 1/2 × b × 7 (multiplying through)

21 = 7b/2

Cross multiply

2 × 21 = 7b

42 = 7b

b = 42/7

b = 6
