m_a_m_a [10]

Answer: (a) 0.317

               (b) 0.167

                (c) Not unusual

Step-by-step explanation:

Probability is defined as the chance of an event occurring.

Let S be a sample space and A be an event in the sample space, the probability of event A occurring can be found using the following:

P(A) = n(A) divided by n(S) where n(A) = number of elements in event A and n(S) = number of elements in the sample space.

(a) P(Right field) = Number of hits to the right field divided by total number of hits

                          = 1919/6060

                          =  19/60  which is approximately equal to 0.317

(b) P(Left field) = 1010/6060

                         = 1/6 which is approximately equal to 0.167

(c)  The probability that the home run was hit to the left field is 0.167.

    The probability of an unusual event is 0, therefore, it is possibly for the

    player to hit a home run to the left.

Sum of all angles is 180 so it is 103+33+x = 180.

so, it is 136+x = 180

x = 180-136 => 44
