Ответ:
0.6
Step-by-step explanation:
0.6 is the answer;this is evident if you draw partially overlapping circles A&B. Place probability 0.3 in the common area (ANB) and 0.4 in the rest of circle A. Place probability 0.1 in the part of B that excludes that ANB area. That leaves 0.2 as outside all circles; you have four different probabilitys that add to 1.0.
