The experimental probability of jessica hitting a softball is 2/5. if she is at bat 50 times in a season, how many times can she be expected to hit the ball?

The probabilty that Jessica will hit the ball after 50 times at bat is 20 times.  

Step-by-step explanation:

Experimental probability represents that chances that something actually happened.  In this case, it represents that for every five times at bat, Jessica hits the ball two times.  Probability is typically expressed as a fraction where the denominator represents the total number of outcomes and the numerator represents the number of desired outcomes, or in this case, how many times she hits the ball.  If we compare 2/5 to our 50 times at bat, which would represent the denominator, we see that we are just multiplying 5 by 10 in which case we would also need to multiply the numerator by 10 in order to get our same probability of 20/50 or 2/5.  

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
