Answer :

The probability that a muffin picked at random contains raisins is : 1/5

Using the parameters given :

  • Number of raisins = 6
  • Total number of muffins = 30

The probability of an event is defined as ;

  • Number of favorable outcomes / Number of total possible outcomes

Now we have ;

P(raisins) = Number of raisins / Total number of muffins

Now we have ;

P(raisins) = 6 / 30

P(raisins) = 1/5

Hence, the probability that a muffin picked at random contains raisins is : 1/5
