Question 1149367
<br>
I will ignore the fact that a batter will never get 9 at bats in one game....<br>
P(7 hits) = {{{(9C7)*(0.181)^7*(1-0.181)^2}}}
P(8 hits) = {{{(9C8)*(0.181)^8*(1-0.181)^1}}}
P(9 hits) = {{{(9C9)*(0.181)^9*(1-0.181)^0}}}<br>
Add the three probabilities....<br>
Or use a graphing calculator that can perform all the calculations for you; or find an online calculator that will calculate these kinds of probabilities.<br>
