Step-by-step explanation:
Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.
By mere guessing p = probability for a right answer = 1/5 =0.20
There are two outcomes and each question is independent of the other.
X no of questions right is Bin (10,0.20)
the probability that the student will pass the test

The equation gives average time spent on 35 rehearsals.
Step-by-step explanation:
We are supposed to find that what question does the equation finds answer of.
We can see that 35x represents time spent on 35 rehearsals and is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
After subtracting hours from 190 hours we will get time spent on 35 rehearsals.
Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation finds average time spent on 35 rehearsals.
