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

Answer:

11a.  m <1 = 131          12a.  m <1 = 42

11b.  m <2 = 49          12b.  m <3 = 75

11c.  m <3 = 131          12c.  m <4 = 42

11d.  m <4 = 49          12d.  m <5 = 63

11e.  m <5 = 131         12e.  m <6 = 75

11f.  m <6 = 49          12f.  m <7 = 105

11g.  m <8 = 49          12g.  m <8 = 75

11h.  m <9 = 92          12h.  m <10 = 75

11i.  m <10 = 88          12i.  m <11 = 42

11j.  m <11 = 92          12j.  m <12 = 138

11k.  m <12 = 88         12k.  m <13 = 42

11l.  m <13 = 92         12l.  m <14 = 138

11m. m <14 = 88

11n.  m <15 = 92

Step-by-step explanation:

When lines are parallel to  each other than:
