1. The probability that I will roll the number exactly three times is 0.0038.

   According to the statement

   we have given that the a six-sided die is rolled a four times and we have to find the probability that I will roll the number exactly three times.

   So, We know that the

   Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

   And the probability of rolling any number on the die is 1/6.

   And

   when i want to get a exactly three number than the probability become:

   So,

   The probability that I will roll the number exactly three times = 1/6 *1/6 *1/6 *5/6

   Then solve it

   The probability that I will roll the number exactly three times = 1/216 * 5/6

   here 5/6 is the probability of that numbers which are not come.

   So,

   The probability that I will roll the number exactly three times = 5/1296

   The probability that I will roll the number exactly three times = 0.0038.

   So, The probability that I will roll the number exactly three times is 0.0038.
