Answer:

25% or 1/4

Step-by-step explanation:

The probability of all correct is [tex]\frac{1}{4}[/tex] or 25%.

Given that,

  • There are 3 questions given i,e a =3.
  • Each question had four choices i.e b = 4.
  • We need to find the probability of all three correct.

According to the situation, calculation of given data are as follows,

Probability of all correct = [tex]\frac{a}{(a \times b )}[/tex]

By putting the value, we get,

Probability = [tex]\frac{3}{(3 \times 4) }[/tex]

= [tex]\frac{3}{12}[/tex]

By simplifying the fraction, we get,

Probability = [tex]\frac{1}{4}[/tex] or 0.25 or 25%.
