Question

a tennis player hits a serve that cannot be returned 45 percent of the time. Out of 300 serves, how many can yiu predict will not be returned?

Answer 1

Remember that 45%=45/100=0.45

So if the tennis player serves the ball 300 times, and 45% cannot be returned, then we can use the following expression to solve for the answer:

300*0.45=135serves

Answer: 135 serves will not be returned
