-0.25=0.75 (former), downward continuation probability is 0.25+q=1 (if less than 1, can go down), the probability is 0.75* (0+2). The sum of the two points and 0.25+0.75*2=1.75 The parent node of 25% is 50%, then 50% is 0.5* (1.75+1), meaning that the child node of this point plus 1 level multiplied by 0.5 is this point value Look at the other 50% (right node), former 0.5, continue down to 0.5* (1.75+2), two points and 3.25 AC Code: public class Main {public static void Main (string[] args)
