Adriving exam consists of 26 multiple-choice questions. each of the 26 answers is either right or wrong. suppose the probability that a student makes fewer than 7 mistakes on the exam is 0.21 and that the probability that a student makes from 7 to 15 (inclusive) mistakes is 0.58. find the probability of each of the following outcomes. a. a student makes more than 15 mistakes

The probability that a student makes more than 15 mistakes is 21% or 0.21

Step-by-step explanation:

To get the probability  of making more than 15 mistakes we have to use the information of the others possibilities

Probability A=Probability of making 7 mistakes on the exam is 0.21

Probability B= Probability that a student makes from 7 to 15 (inclusive) mistakes is 0.58.

Probability C=The other option is making more than 15 mistakes.

We consider we have only those 3 options so they have to make the 100%

3 options =100%= probability A + Probability B+ Probability C

Then,  Probability C= 100%-probability A - Probability B

Probability C= 100%-21% - 58%

Probability C= 21%

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
