Answer:
1/10
Step-by-step explanation:
P(a successful member
had Bertha as her trainer)  = P(Bertha being you trainer) x P(being successful if
                                                 trained by Bertha)
                                              = 1/3 x 30/100
                                              = 30/300
                                              = 1/10
 
        
             
        
        
        
Answer:

Step-by-step explanation:
1) the rule of transformation [degr → rad] is:
![\alpha [rad]=\alpha [degr] *\frac{\pi }{180};](https://tex.z-dn.net/?f=%5Calpha%20%5Brad%5D%3D%5Calpha%20%5Bdegr%5D%20%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3B)
2) according to the formula above:
230°=230*π/180=23π/18 [rad].
