You can put this solution on YOUR website! Two basketball players, A and B, have probabilities of .8 and .7 of making a shot on any given trial, respectively. Assume that the events are independent. If A and B shoot twice (each), what is the probability that at least 1 shot will be made?
------
P(at least one made) = 1 - P(both shooters miss 2 shots)
---
= 1 - [0.2^2+0.3^2]
---------------
= 1 - [0.04+0.09]
----
= 1 - [0.13]
---
= 0.87
