The answer to the question is 21/3
Answer:
The answer is B. He spent 3 minutes eating lunch for every 10 minutes.
Step-by-step explanation:
He spent stuck inside during the brainstorm for:
20+18+12+10= 60 minutes in total.
And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:
And now we can multiply the time of the activities by 1/6 to get the time he did each activity every 10 minutes.
Reading:
minutes reading for every 10 minutes.
Eating:
minutes eating for every 10 minutes.
Watching TV:
minutes watching TV for every 10 minutes.
Drawing:
minutes drawing for every 10 minutes.
Therefore he spent 3 minutes eating lunch for every 10 minutes.
0.12 = 12/100 = 6/50 =3/25
0.12 =3/25

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.
