Lourdes has 3times as much money than ella. Together they have $32 . How much money does Lourdes have ?

Mariana [72]

Answer:

Lourdes has $24.

Step-by-step explanation:

The appropriate equation would be L + (L/3) = $32, or 3L + L = $96.

Solving for L: 4L = $96, and L = $24. This is 3x what Ella has, so Ella has $8.

Check: Do $8 and $24 add up to $32? YES

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

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

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

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