schepotkina [342]

Answer:

0.966

Step-by-step explanation:

Given that:

Probability of DVD player breaking down before the warranty expires = 0.034

To find:

The probability that the player will not break down before the warranty expires = ?

Solution:

Here, The two events are:

1. The DVD player breaks down before the warranty gets expired.

2. The DVD player breaks down after the warranty gets expired

In other words, the 2nd event can be stated as:

The DVD does not break down before the warranty gets expired.

The two events here, have nothing in common i.e. they are mutually exclusive events.

So, Sum of their probabilities will be equal to 1.

\bold{P(E_1)+P(E_2)=1}\\\Rightarrow 0.034+P(E_2)=1\\\Rightarrow P(E_2)=1-0.034\\\Rightarrow P(E_2)=\bold{0.966}

Lisa and her daughter weigh 185 pounds all together. The ratio of lisa’s weight to her daughter weight is 4:1 . How much does li
frez [133]

Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.

In fact, if the daughter weights d pound, the mother weights 4d pounds, and the total weight is d+4d = 5d.

We know that this total is 185 pounds, so we have

5d = 185 \iff d = \dfrac{185}{5} = 37

So, the daughter weights 37 pounds.
