Answer:
The probability of the student incorrectly solves the next problem is 44%.
Step-by-step explanation:
Let E be the event of solving a problem correctly.
Then E' is the event that the problem is solved incorrectly.
Now, recall the definition of probability.
probability of an event =
So,
p(E) =
Also,
p(E) + p(E') = 1 and
p(E') = 1 - p(E)
= 1 -
=
=
=
=
= 44% rounded.
Hence, the probability of the student incorrectly solves the next problem is 44%.
