Remark

An angle bisector sets up a triangle ratio that looks like the following proportion.

3x - 3 5x

====== = ====== Cross multiply

24 44

44*(3x-3) = 24*5x Remove the brackets on the left

132x - 132 = 24*5x Combine the right side

132x - 132 = 120x Add 132 to both sides

132x = 120x + 132 Subtract 120x from both sides

132x- 120x = 132 Combine

12x = 132 Divide by 12

x = 11

C and D are mutually exclusive events. Find P(C or D).<br> P(C)= 3/7= P(D)= 4/7<br> P(C or D)

IgorLugansk [536]

Answer:

$P(C\ or\ D) = 1$

Step-by-step explanation:

Given

$P(C) = \frac{3}{7}$

$P(D) = \frac{4}{7}$

Required

$P(C\ or\ D)$

Since the events are mutually exclusive, then:

$P(C\ or\ D) = P(C) + P(D)$

So, we have:

$P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}$

Take LCM

$P(C\ or\ D) = \frac{3+4}{7}$

$P(C\ or\ D) = \frac{7}{7}$

$P(C\ or\ D) = 1$
